Description
The TLV320AIC3111 is a low-power, highly
integrated, high-performance codec which provides a
stereo audio DAC and mono audio ADC.
The TLV320AIC3111 features a high-performance
audio codec with 16-bit stereo playback and
monaural record functionality. The device integrates
several analog features, such as a microphone
interface, headphone drivers, and speaker drivers.
The TLV320AIC3111 has a fully programmable
miniDSP for digital audio processing. The digital
audio data format is programmable to work with
popular audio standard protocols (I2S, left-/ rightjustified) in master, slave, DSP, and TDM modes.
Bass boost, treble, or EQ can be supported by the
programmable digital signal-processing block.
An on-chip PLL provides the high-speed clock
needed by the digital signal processing block. The
volume level can be controlled by either pin control or
by register control. The audio functions are controlled
using the I2C serial bus.
The TLV320AIC3111 has a programmable beep
generator and is available in a 32-pin QFN package.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

To minimize battery-current leakage, the SPLVDD and SPRVDD voltage levels should not be below the AVDD voltage level.
All grounds on board are tied together, so they should not differ in voltage by more than 0.2 V maximum for any combination of ground
signals. By use of a wide trace or ground plane, ensure a low-impedance connection between HPVSS and DVSS.
The maximum input frequency should be 50 MHz for any digital pin used as a general-purpose clock.

All performance measurements done with 20-kHz low-pass filter and, where noted, A-weighted filter. Failure to use such a filter may
result in higher THD+N and lower SNR and dynamic range readings than shown in the Electrical Characteristics. The low-pass filter
removes out-of-band noise, which, although not audible, may affect dynamic specification values.
DAC to headphone-out PSRR measurement is calculated as PSRR = 20 × log(ΔVHPL / ΔVHPVDD).

Overview
The TLV320AIC3111 is a highly integrated stereo audio DAC and monaural ADC for portable computing,
communication, and entertainment applications. A register-based architecture eases integration with
microprocessor-based systems through standard serial-interface buses. This device supports the 2-wire
I2C bus interface which provides full register access. All peripheral functions are controlled through these
registers and the onboard state machines.
The TLV320AIC3111 consists of the following blocks:
• Microphone interfaces (analog and digital)
• Audio codec (mono ADC and stereo DAC)

Following a toggle of the RESET pin or a software reset, the device operates in the default mode. The I2C
interface is used to write to the control registers to configure the device.
The I2C address assigned to the TLV320AIC3111 is 001 1000. This device always operates in an I2C
slave mode. All registers are 8-bit, and all writable registers have read-back capability. The device autoincrements to support sequential addressing and can be used with I2C fast mode. Once the device is
reset, all appropriate registers are updated by the host processor to configure the device as needed by the
user.
5.2.1
Device Initialization
5.2.1.1
Reset
The TLV320AIC3111 internal logic must be initialized to a known condition for proper device function. To
initialize the device to its default operating condition, the hardware reset pin (RESET) must be pulled low
for at least 10 ns. For this initialization to work, both the IOVDD and DVDD supplies must be powered up.
It is recommended that while the DVDD supply is being powered up, the RESET pin be pulled low.
The device can also be reset via software reset. Writing a 1 into page 0 / register 1, bit D0 resets the
device.
5.2.1.2
Device Start-Up Lockout Times
After the TLV320AIC3111 is initialized through hardware reset at power up or software reset, the internal
memories are initialized to default values. This initialization takes place within 1 ms after pulling the
RESET signal high. During this initialization phase, no register-read or register-write operation should be
performed on ADC or DAC coefficient buffers. Also, no block within the codec should be powered up
during the initialization phase.
5.2.1.3
PLL Start-Up
Whenever the PLL is powered up, a start-up delay of approximately of 10 ms occurs after the power-up
command of the PLL and before the clocks are available to the codec. This delay is to ensure stable
operation of the PLL and clock-divider logic.
5.2.1.4
Power-Stage Reset
The power-stage-only reset is used to reset the device after an overcurrent latching shutdown has
occurred. Using this reset re-enables the output stage without resetting all of the registers in the device.
Each of the four power stages has its own dedicated reset bit. The headphone power-stage reset is
performed by setting page 1 / register 31, bit D7 for HPL and by setting page 1 / register 31, bit D6 for
HPR. The speaker power-stage reset is performed by setting page 1 / register 32, bit D7 for SPLP and
SPLM, and by setting page 1 / register 32, bit D6 for SPRP and SPRM.

5.2.1.5
SLAS644D – JULY 2009 – REVISED MAY 2012
Software Power Down
By default, all circuit blocks are powered down following a reset condition. Hardware power up of each
circuit block can be controlled by writing to the appropriate control register. This approach allows the
lowest power-supply current for the functionality required. However, when a block is powered down, all of
the register settings are maintained as long as power is still being applied to the device.
5.2.2
Audio Analog I/O
The TLV320AIC3111 has a stereo audio DAC and a monaural ADC. It supports a wide range of analog
interfaces to support different headsets and analog outputs. The TLV320AIC3111 has features to interface
output drivers (8-Ω, 16-Ω, 32-Ω) and a microphone PGA with AGC control. A special circuit has also been
included in the TLV320AIC3111 to insert a short key-click sound into the stereo audio output. The keyclick sound is used to provide feedback to the user when a particular button is pressed or item is selected.
The specific sound of the keyclick can be adjusted by varying several register bits that control its
frequency, duration, and amplitude. See Key-Click Functionality With Beep Generator, Section 5.6.7.
5.3
miniDSP
The TLV320AIC3111 features two miniDSP cores. The first miniDSP core is tightly coupled to the ADC;
the second miniDSP core is tightly coupled to the DAC. The fully programmable algorithms for the
miniDSP must be loaded into the device after power up. The miniDSPs have direct access to the digital
stereo audio stream on the ADC and on the DAC side, offering the possibility for advanced, very lowgroup-delay DSP algorithms.
The ADC miniDSP has 384 programmable instructions, 256 data memory locations, and 128
programmable coefficients. The DAC miniDSP has 1024 programmable instructions, 896 data memory
locations, and 512 programmable coefficients (in the adaptive mode, each bank has 256 programmable
coefficients).
5.3.1
Software
Software development for the TLV320AIC3111 is supported through TI's comprehensive PurePath™
Studio software development environment, a powerful, easy-to-use tool designed specifically to simplify
software development on Texas Instruments miniDSP audio platforms. The graphical development
environment consists of a library of common audio functions that can be dragged and dropped into an
audio signal flow and graphically connected together. The DSP code can then be assembled from the
graphical signal flow with the click of a mouse.
See the TLV320AIC3111 product folder on www.ti.com to learn more about PurePath Studio software and
the latest status on available, ready-to-use DSP algorithms.
5.4
Digital Processing Low-Power Modes
The TLV320AIC3111 device can be tuned to minimize power dissipation, to maximize performance, or to
an operating point between the two extremes to best fit the application. The choice of processing blocks,
PRB_P1 to PRB_P25 for stereo playback and PRB_R4 to PRB_R18 for mono recording, also influences
the power consumption. In fact, the numerous processing blocks have been implemented to offer a choice
among configurations having a different balance of power optimization and signal-processing capabilities.

Audio ADC and Analog Inputs
5.5.1
MICBIAS and Microphone Preamplifier
The TLV320AIC3111 includes a microphone bias circuit which can source up to 4 mA of current and is
programmable to a 2-V, 2.5-V, or AVDD level. The level can be controlled by writing to page 1 /
register 46, bits D1–D0. This functionality is shown in Table 5-14.

MICBIAS output is powered to AVDD.
During normal operation, MICBIAS can be set to 2.5 V for better performance. However, depending on the
model of microphone that is selected, optimal performance might be obtained at another setting, so the
performance at a given setting should be verified.
The lowest current consumption occurs when MICBIAS is powered down. The next-lowest current
consumption occurs when MICBIAS is set at AVDD.
Because of the oversampling nature of the audio ADC and the integrated digital decimation filtering,
requirements for analog anti-aliasing filtering are very relaxed. The TLV320AIC3111 integrates a secondorder analog anti-aliasing filter with 20-dB attenuation at 1 MHz. This filter, combined with the digital
decimal filter, provides sufficient anti-aliasing filtering without requiring any external components.
The MIC PGA supports analog gain control from from 0 dB to 59.5 dB in steps of 0.5 dB. These gain
levels can be controlled by writing to page 1 / register 47, bits D6–D0. The PGA gain changes are
implemented with internal soft-stepping. This soft-stepping ensures that volume-control changes occur
smoothly with no audible artifacts. On reset, the MIC PGA gain defaults to a mute condition, with softstepping enabled. The ADC soft-stepping control can be enabled or disabled by writing to page 0 /
register 81, bits D1–D0. ADC soft-stepping timing is provided by the internal oscillator and internal divider
logic block.
The input feed-forward resistance for the MIC1LP input of the microphone PGA stage has three settings,
10 kΩ, 20 kΩ, and 40 kΩ, which are controlled by writing to page 1 / register 48, bits D7 and D6. The input
feed-forward resistance value selected affects the gain of the microphone PGA. The ADC PGA gain for
the MIC1LP input depends on the setting of page1 / register 48 and page 1 / register 49, bits D7–D6. If
D7–D6 are set to 01, then the ADC PGA has 6 dB more gain with respect to the value programmed using
page 1 / register 47. If D7–D6 are set to 10, then the ADC PGA has the same gain as programmed using
page 1 / register 47. If D7–D6 are set to 11, then the ADC PGA has 6 dB less gain with respect to the
value programmed using page 1 / register 47. The same gain scaling is also valid for the MIC1RP and
MIC1LM input, based on the feed-forward resistance selected using page 1 / register 48, bits D5–D2.

The MIC PGA gain can be controlled either by an AGC loop or as a fixed gain. See Figure 1-1 for the
various analog input routings to the MIC PGA that are supported in the single-ended and differential
configurations. The AGC can be enabled by writing to page 0 / register 86, bit D7. If the AGC is not
enabled, then setting a fixed gain is done by writing to page 1 / register 47, bits D6–D0. Because the
TLV320AIC3111 supports soft-stepping gain changes, a read-only flag on page 0 / register 36, bit D7 is
set whenever the gain applied by PGA equals the desired value set by the gain register. The MIC PGA
can be enabled by writing to page 1 / register 47, bit D7. ADC muting can be done by writing to page 0 /
register 82, bit D7 and page 1 / register 47, bit D7. Disabling the MIC PGA sets the gain to 0 dB. Muting
the ADC causes the digital output to mute so that the output value remains fixed. When soft-stepping is
enabled, the CODEC_CLKIN signal must stay active until after the ADC power-down register is written, in
order to ensure that soft-stepping to mute has had time to complete. When the ADC POWER UP flag is
no longer set, the CODEC_CLKIN signal can be shut down.
5.5.2
Automatic Gain Control (AGC)
The TLV320AIC3111 includes automatic gain control (AGC) for the microphone inputs. AGC can be used
to maintain nominally constant output-signal amplitude when recording speech signals. This circuitry
automatically adjusts the MIC PGA gain as the input signal becomes overly loud or very weak, such as
when a person speaking into a microphone moves closer to or farther from the microphone. The AGC
algorithm has several programmable settings, including target gain, attack and decay time constants,
noise threshold, and maximum PGA applicable, that allow the algorithm to be fine-tuned for any particular
application. The algorithm uses the absolute average of the signal (which is the average of the absolute
value of the signal) as a measure of the nominal amplitude of the output signal. Because the gain can be
changed at the sample interval time, the AGC algorithm operates at the ADC_fS clock rate.
Target level represents the nominal output level at which the AGC attempts to hold the ADC output
signal. The TLV320AIC3111 allows programming of eight different target levels, which can be
programmed from –5.5 dB to –24 dB relative to a full-scale signal. Because the TLV320AIC3111 reacts to
the signal absolute average and not to peak levels, it is recommended that the target level be set with
enough margin to avoid clipping at the occurrence of loud sounds.
An AGC low-pass filter is used to help determine the average level of the input signal. This average level
is compared to the programmed detection levels in the AGC to provide the correct functionality. This lowpass filter is in the form of a first-order IIR filter. Programming this filter is done by writing to page 4 /
register 2 through page 4 / register 7. Two 8-bit registers are used to form the 16-bit digital coefficient as
shown on the register map. In this way, a total of six registers are programmed to form the three IIR
coefficients.
Attack time determines how quickly the AGC circuitry reduces the PGA gain when the input signal is too
loud. Programming the attack time is done by writing to page 0 / register 89, bits D7–D0.
Decay time determines how quickly the PGA gain is increased when the input signal is too low.
Programming the decay time is done by writing to page 0 / register 90, bits D7–D0.
Noise threshold is a reference level. If the input speech average value falls below the noise threshold,
the AGC considers it as a silence and hence brings down the gain to 0 dB in steps of 0.5 dB every sample
period and sets the noise-threshold flag. The gain stays at 0 dB unless the input speech signal average
rises above the noise-threshold setting. This ensures that noise is not amplified in the absence of speech.
The noise-threshold level in the AGC algorithm is programmable from –30 dB to –90 dB for the
microphone input. When the AGC noise threshold is set to –70 dB, –80 db, or –90 dB, the microphone
input maximum PGA applicable setting must be greater than or equal to 11.5 dB, 21.5 dB, or 31.5 dB,
respectively. This operation includes debounce and hysteresis to prevent the AGC gain from cycling
between high gain and 0 dB when signals are near the noise threshold level. When the noise-threshold
flag is set, the status of the gain applied by the AGC and the saturation flag should be ignored.
Programming the noise debounce is done by writing to page 0 / register 91, bits D4–D0. Programming the
signal debounce is done by writing to page 0 / register 92, bits D3–D0.

Max PGA applicable allows the user to restrict the maximum gain applied by the AGC. This can be used
for limiting PGA gain in situations where environmental noise is greater than the programmed noise
threshold. Microphone input maximum PGA can be programmed from 0 dB to 59.5 dB in steps of 0.5 dB.
Programming the maximum PGA gain allowed by the AGC is done by writing to page 0 / register 88,
bits D6–D0.
See Table 5-16 for various AGC programming options. AGC can be used only if the microphone input is
routed to the ADC channel.

Delta-Sigma ADC
The analog-to-digital converter has a delta-sigma modulator with an oversampling ratio (AOSR) up to 128.
The ADC can support a maximum output rate of 192 kHz.
ADC power up is controlled by writing to page 0 / register 81, bit D7. An ADC power-up condition can be
verified by reading page 0 / register 36, bit D6.
5.5.4
ADC Decimation Filtering and Signal Processing
The TLV320AIC3111 ADC channel includes built-in digital decimation filters to process the oversampled
data from the delta-sigma modulator to generate digital data at the Nyquist sampling rate with high
dynamic range. The decimation filter can be chosen from three different types, depending on the required
frequency response, group delay, and sampling rate.
5.5.4.1
ADC Processing Blocks
The TLV320AIC3111 offers a range of processing blocks which implement various signal processing
capabilities along with decimation filtering. These processing blocks give users the choice of how much
and what type of signal processing they may use and which decimation filter is applied.
The choices among these processing blocks allow the system designer to balance power conservation
and signal-processing flexibility. Less signal-processing capability reduces the power consumed by the
device. Table 5-17 gives an overview of the available processing blocks of the ADC channel and their
properties. The Resource Class (RC) column gives a relative indication of power consumption.
The signal processing blocks available are:
• First-order IIR
• Scalable number of biquad filters
• Variable-tap FIR filter
• AGC
The processing blocks are tuned for common cases and can achieve high anti-alias filtering or low group
delay in combination with various signal-processing effects such as audio effects and frequency shaping.
The available first-order IIR, biquad, and FIR filters have fully user-programmable coefficients.

ADC Digital Decimation Filter Characteristics
The TLV320AIC3111 offers three different types of decimation filters. The integrated digital decimation
filter removes high-frequency content and downsamples the audio data from an initial sampling rate of
AOSR × fS to the final output sampling rate of fS. The decimation filtering is achieved using a higher-order
CIC filter followed by linear-phase FIR filters. The decimation filter cannot be chosen by itself; it is implicitly
set through the chosen processing block.
The following subsections describe the properties of the available filters A, B, and C.
5.5.4.4.1 Decimation Filter A
This filter is intended for use at sampling rates up to 48 kHz. When configuring this filter, the oversampling
ratio of the ADC can either be 128 or 64. For highest performance, the oversampling ratio must be set
to 128.
Filter A can also be used for 96 kHz at an AOSR of 64.

ADC Data Interface
The decimation filter and signal processing block in the ADC channel pass 32-bit data words to the audio
serial interface once every cycle of ADC_fS. During each cycle of ADC_fS, a pair of data words (for left
and right channel) is passed. The audio serial interface rounds the data to the required word length of the
interface before converting to serial data. Because the TLV320AIC3111 has only a mono ADC, it passes
the same data to both the left and right channels of the audio serial interface.
5.5.5
Updating ADC Digital Filter Coefficients During Record
When it is required to update the ADC digital filter coefficients during record, care must be taken to avoid
click and pop noise or even a possible oscillation noise. These artifacts can occur if the ADC coefficients
are updated without following the proper update sequence. The correct sequence is shown in Figure 5-16.
The values for the times listed are conservative and should be used for software purposes.

When the digital microphone mode is enabled, the analog section of the ADC can be powered down and

desired decimation ratio to be achieved, based on the external digital microphone properties.
5.5.7
DC Measurement
The TLV320AIC3111 supports a highly flexible dc-measurement mode using the high-resolution
oversampling and noise-shaping ADC. This mode can be used when the ADC channel is not used for the
voice/audio record function. This mode can be enabled by programming page 0 / register 102, bit D7. The
converted data is 24 bits, using the 2.22 numbering format. The value of the converted data for the ADC
channel can be read back from page 0 / register 104 through page 1 / register 106. Before reading back
the converted data, page 0 / register 103, bit D6 must be programmed to 1 in order to latch the converted
data into the read-back registers. After the converted data is read back, page 0 / register 103, bit D6 must
be immediately reset to 0. In dc-measurement mode, two measurement modes are supported.
Mode A
In dc-measurement mode A, a variable-length averaging filter is used. The length of averaging filter D can
be programmed from 1 to 20 by programming page 0 / register 102, bits D4–D0. To choose mode A,
page 0 / register 102, bit D5 must be programmed to 0.

By programming page 0 / register 103, bit D5 to 1, the averaging filter is periodically reset after 2R number
of ADC_MOD_CLK periods, where R is programmed in page 0 / register 103, bits D4–D0. When page 0 /
register 103, bit D5 is set to 1, then the value of D should be less than the value of R. When page 0 /
register 103, bit D5 is programmed to 0, the averaging filter is never reset.
5.6
Audio DAC and Audio Analog Outputs
Each channel of the stereo audio DAC consists of a digital audio processing block, a digital interpolation
filter, a digital delta-sigma modulator, and an analog reconstruction filter. This high oversampling ratio
(normally DOSR is between 32 and 128) exhibits good dynamic range by ensuring that the quantization
noise generated within the delta-sigma modulator stays outside of the audio frequency band. Audio analog
outputs include stereo headphone/lineouts and stereo class-D speaker outputs.
5.6.1
DAC
The TLV320AIC3111 stereo audio DAC supports data rates from 8 kHz to 192 kHz. Each channel of the
stereo audio DAC consists of a signal-processing engine with fixed processing blocks, a programmable
miniDSP, a digital interpolation filter, multibit digital delta-sigma modulator, and an analog reconstruction
filter. The DAC is designed to provide enhanced performance at low sampling rates through increased
oversampling and image filtering, thereby keeping quantization noise generated within the delta-sigma

modulator and signal images strongly suppressed within the audio band to beyond 20 kHz. To handle
multiple input rates and optimize power dissipation and performance, the TLV320AIC3111 allows the
system designer to program the oversampling rates over a wide range from 1 to 1024 by configuring
page 0 / register 13 and page 0 / register 14. The system designer can choose higher oversampling ratios
for lower input data rates and lower oversampling ratios for higher input data rates.
The TLV320AIC3111 DAC channel includes a built-in digital interpolation filter to generate oversampled
data for the delta-sigma modulator. The interpolation filter can be chosen from three different types,
depending on required frequency response, group delay, and sampling rate.
DAC power up is controlled by writing to page 0 / register 63, bit D7 for the left channel and bit D6 for the
right channel. The left-channel DAC clipping flag is provided as a read-only bit on page 0 / register 39,
bit D7. The right-channel DAC clipping flag is provided as a read-only bit on page 0 / register 39, bit D6.
5.6.1.1
DAC Processing Blocks
The TLV320AIC3111 implements signal-processing capabilities and interpolation filtering via processing
blocks. These fixed processing blocks give users the choice of how much and what type of signal
processing they use and which interpolation filter is applied.
The choices among these processing blocks allow the system designer to balance power conservation
and signal-processing flexibility. Table 5-25 gives an overview of all available processing blocks of the
DAC channel and their properties. The resource-class column gives an approximate indication of power
consumption for the digital (DVDD) supply; however, based on the out-of-band noise spectrum, the analog
power consumption of the drivers (HPVDD) may differ.
The signal processing blocks available are:
• First-order IIR
• Scalable number of biquad filters
• 3D effect
• Beep generator
The processing blocks are tuned for common cases and can achieve high image rejection or low group
delay in combination with various signal-processing effects such as audio effects and frequency shaping.
The available first-order IIR and biquad filters have fully user-programmable coefficients.

DAC User-Programmable Filters
Depending on the selected processing block, different types and orders of digital filtering are available. Up
to six biquad sections are available for specific processing blocks.
The coefficients of the available filters are arranged as sequentially-indexed coefficients in two banks. If
adaptive filtering is chosen, the coefficient banks can be switched on-the-fly.
When the DAC is running, the user-programmable filter coefficients are locked and cannot be accessed
for either read or write.
However, the TLV320AIC3111 offers an adaptive filter mode as well. Setting page 8 / register 1, bit D2 = 1
turns on double buffering of the coefficients. In this mode, filter coefficients can be updated through the
host and activated without stopping and restarting the DAC. This enables advanced adaptive filtering
applications.
In the double-buffering scheme, all coefficients are stored in two buffers (buffers A and B). When the DAC
is running and the adaptive filtering mode is turned on, setting page 8 / register 1, bit D0 = 1 switches the
coefficient buffers at the next start of a sampling period. This bit is set back to 0 after the switch occurs. At
the same time, page 8 / register 1, bit D1 toggles.
The flag in page 8 / register 1, bit D1 indicates which of the two buffers is actually in use.
Page 8 / register 1, bit D1 = 0: buffer A is in use by the DAC engine; bit D1 = 1: buffer B is in use.
While the device is running, coefficient updates are always made to the buffer not in use by the DAC,
regardless of the buffer to which the coefficients have been written.

The user-programmable coefficients C1 to C70 are defined on pages 8, 9, 10, and 11 for buffer A and
pages 12, 13, 14, and 15 for buffer B.
The coefficients of these filters are each 16-bit, 2s-complement format, occupying two consecutive 8-bit
registers in the register space. Specifically, the filter coefficients are in 1.15 (one dot 15) format with a
range from –1.0 (0x8000) to 0.999969482421875 (0x7FFF) as shown in Figure 5-12.

DAC Digital-Volume Control
The DAC has a digital-volume control block which implements programmable gain. Each channel has an
independent volume control that can be varied from 24 dB to –63.5 dB in 0.5-dB steps. The left-channel
DAC volume can be controlled by writing to page 0 / register 65, bits D7–D0. The right-channel DAC
volume can be controlled by writing to page 0 / register 66, bits D7–D0. DAC muting and setting up a
master gain control to control both channels is done by writing to page 0 / register 64, bits D3–D0. The
gain is implemented with a soft-stepping algorithm, which only changes the actual volume by 0.125 dB per
input sample, either up or down, until the desired volume is reached. The rate of soft-stepping can be
slowed to one step per two input samples by writing to page 0 / register 63, bits D1–D0. Note that the
default source for volume-control level settings is control by register writes (page 0 / register 65 and
page 0 / register 66 to control volume). Use of the VOL/MICDET pin to control the DAC volume is ignored
until the volume control source selected has been changed to pin control (page 0 / register 116, bit
D7 = 1). This functionality is shown in Figure 1-1.
During soft-stepping, the host does not receive a signal when the DAC has been completely muted. This
may be important if the host must mute the DAC before making a significant change, such as changing
sample rates. In order to help with this situation, the device provides a flag back to the host via a readonly register, page 0 / register 38, bit D4 for the left channel and bit D0 for the right channel. This
information alerts the host when the part has completed the soft-stepping and the actual volume has
reached the desired volume level. The soft-stepping feature can be disabled by writing to page 0 /
register 63, bits D1–D0.
If soft-stepping is enabled, the CODEC_CLKIN signal should be kept active until the DAC power-up flag is
cleared. When this flag is cleared, the internal DAC soft-stepping process is complete, and
CODEC_CLKIN can be stopped if desired. (The analog volume control can be ramped down using an
internal oscillator.)

Volume-Control Pin
The volume-control pin is not enabled by default but it can be enabled by writing 1 to page 0 /
register 116, bit D7. The default DAC volume control uses software control of the volume, which occurs if
page 0 / register 116, bit D7 = 0. Soft-stepping the volume level is set up by writing to page 0 / register 63,
bits D1–D0.
When the volume-pin function is used, a 7-bit Vol ADC reads the voltage on the VOL/MICDET pin and
updates the digital volume control. (It overwrites the current value of the volume control.) The new volume
setting which has been applied due to a change of voltage on the volume control pin can be read on
page 0 / register 117, bits D6–D0. The 7-bit Vol ADC clock source can be selected on page 0 /
register 116, bit D6. The update rate can be programmed on page 0 / register 116, bits D2–D0 for this 7bit SAR ADC.
The VOL/MICDET pin gainmapping is shown in Table 5-32.

Figure 5-33. Digital Volume Controls for Beep Generator and DAC Play Data
As shown in Table 5-32, the VOL/MICDET pin has a range of volume control from 18 dB down to –63 dB,
and mute. However, if less maximum gain is required, then a smaller range of voltage should be applied
to the VOL/MICDET pin. This can be done by increasing the value of R2 relative to the value of (P1 + R1),
so that more voltage is available at the bottom of P1. The circuit should also be designed such that for the
values of R1, R2, and P1 chosen, the maximum voltage (top of the potentiometer) does not exceed
AVDD/2 (see Figure 5-33). The recommended values for R1, R2, and P1 for several maximum gains are
shown in Table 5-33. Note that in typical applications, R1 should not be 0 Ω, as the VOL/MICDET pin
should not exceed AVDD/2 for proper ADC operation.

Dynamic Range Compression
Typical music signals are characterized by crest factors, the ratio of peak signal power to average signal
power, of 12 dB or more. To avoid audible distortions due to clipping of peak signals, the gain of the DAC
channel must be adjusted so as not to cause hard clipping of peak signals. As a result, during nominal
periods, the applied gain is low, causing the perception that the signal is not loud enough. To overcome
this problem, dynamic range conpression (DRC) in the TLV320AIC3111 continuously monitors the output
of the DAC digital volume control to detect its power level relative to 0 dBFS. When the power level is low,
DRC increases the input signal gain to make it sound louder. At the same time, if a peaking signal is
detected, it autonomously reduces the applied gain to avoid hard clipping. This results in sounds more
pleasing to the ear as well as sounding louder during nominal periods.
The DRC functionality in the TLV320AIC3111 is implemented by a combination of processing blocks in the
DAC channel as described in Section 5.6.1.2.

DRC can be disabled by writing to page 0 / register 68, bits D6–D5.
DRC typically works on the filtered version of the input signal. The input signals have no audio information
at dc and extremely low frequencies; however, they can significantly influence the energy estimation
function in the dynamic range compressor (the DRC). Also, most of the information about signal energy is
concentrated in the low-frequency region of the input signal.
To estimate the energy of the input signal, the signal is first fed to the DRC high-pass filter and then to the
DRC low-pass filter. These filters are implemented as first-order IIR filters given by
HHPF (z) =
HLPF (z) =
N0 + N1z -1
215 - D1z -1
N0 + N1z
(6)
-1
215 - D1z -1
(7)
The coefficients for these filters are 16 bits wide in 2s-complement format and are user-programmable
through register write as given in Table 5-34.

The default values of these coefficients implement a high-pass filter with a cutoff at 0.00166 × DAC_fS,
and a low-pass filter with a cutoff at 0.00033 × DAC_fS.
The output of the DRC high-pass filter is fed to the processing block selected for the DAC channel. The
absolute value of the DRC LPF filter is used for energy estimation within the DRC.
The gain in the DAC digital volume control is controlled by page 0 / register 65 and page 0 / register 66.
When the DRC is enabled, the applied gain is a function of the digital volume control register setting and
the output of the DRC.
The DRC parameters are described in sections that follow.
5.6.4.1
DRC Threshold
DRC threshold represents the level of the DAC playback signal at which the gain compression becomes
active. The output of the digital volume control in the DAC is compared with the set threshold. The
threshold value is programmable by writing to page 0 / register 68, bits D4–D2. The threshold value can
be adjusted between –3 dBFS and –24 dBFS in steps of 3 dB. Keeping the DRC threshold value too high
may not leave enough time for the DRC block to detect peaking signals, and can cause excessive
distortion at the outputs. Keeping the DRC threshold value too low can limit the perceived loudness of the
output signal.
The recommended DRC threshold value is –24 dB.
When the output signal exceeds the set DRC threshold, the interrupt flag bits at page 0 / register 44,
bits D3–D2 are updated. These flag bits are sticky in nature, and are reset only after they are read back
by the user. The non-sticky versions of the interrupt flags are also available at page 0 / register 46,
bits D3–D2.

DRC Hysteresis
DRC hysteresis is programmable by writing to page 0 / register 68, bits D1–D0. These bits can be
programmed to represent values between 0 dB and 3 dB in steps of 1dB. It is a programmable window
around the programmed DRC threshold that must be exceeded for the disabled DRC to become enabled,
or the enabled DRC to become disabled. For example, if the DRC threshold is set to –12 dBFS and the
DRC hysteresis is set to 3 dB, then if the gain compression in the DRC is inactive, the output of the DAC
digital volume control must exceed –9 dBFS before gain compression due to the DRC is activated.
Similarly, when the gain compression in the DRC is active, the output of the DAC digital volume control
must fall below –15 dBFS for gain compression in the DRC to be deactivated. The DRC hysteresis feature
prevents the rapid activation and de-activation of gain compression in the DRC in cases when the output
of the DAC digital volume control rapidly fluctuates in a narrow region around the programmed DRC
threshold. By programming the DRC hysteresis as 0 dB, the hysteresis action is disabled.
The recommended value of DRC hysteresis is 3 dB.
5.6.4.3
DRC Hold
DRC hold is intended to slow the start of decay for a specified period of time in response to a decrease in
energy level. To minimize audible artifacts, it is recommended to set the DRC hold time to 0 through
programming page 0 / register 69, bits D6–D3 = 0000.
5.6.4.4
DRC Attack Rate
When the output of the DAC digital volume control exceeds the programmed DRC threshold, the gain
applied in the DAC digital volume control is progressively reduced to avoid the signal from saturating the
channel. This process of reducing the applied gain is called attack. To avoid audible artifacts, the gain is
reduced slowly with a rate equaling the attack rate, programmable via page 0 / register 70, bits D7–D4.
Attack rates can be programmed from 4-dB gain change per 1/DAC_fS to 1.2207e–5-dB gain change
per 1/DAC_fS.
Attack rates should be programmed such that before the output of the DAC digital volume control can clip,
the input signal should be sufficiently attenuated. High attack rates can cause audible artifacts, and tooslow attack rates may not be able to prevent the input signal from clipping.
The recommended DRC attack rate value is 1.9531e–4 dB per 1/DAC_fS.
5.6.4.5
DRC Decay Rate
When the DRC detects a reduction in output signal swing beyond the programmed DRC threshold, the
DRC enters a decay state, where the applied gain in the digital-volume control is gradually increased to
programmed values. To avoid audible artifacts, the gain is slowly increased with a rate equal to the decay
rate programmed through page 0 / register 70, bits D3–D0. The decay rates can be programmed from
1.5625e–3 dB per 1/DAC_fS to 4.7683e–7 dB per 1/DAC_fS. If the decay rates are programmed too high,
then sudden gain changes can cause audible artifacts. However, if it is programmed too slow, then the
output may be perceived as too low for a long time after the peak signal has passed.
The recommended value of DRC decay rate is 2.4414e–5 dB per 1/DAC_fS.

This feature is enabled by programming page 0 / register 67, bit D1. In order to avoid false detections due
to mechanical vibrations in headset jacks or microphone buttons, a debounce function is provided for
glitch rejection. For the case of headset insertion, a debounce function with a range of 32 ms to 512 ms is
provided. This can be programmed via page 0 / register 67, bits D4–D2. For improved button-press
detection, the debounce function has a range of 8 ms to 32 ms by programming page 0 / register 67,
bits D1–D0.
The TLV320AIC3111 also provides feedback to the user through register-readable flags as well as an
interrupt on the I/O pins when a button press or a headset insertion/removal event is detected. The value
in page 0 / register 46, bits D5–D4 provides the instantaneous state of button press and headset insertion.
Page 0 / register 44, bit D5 is a sticky (latched) flag that is set when the button-press event is detected.
Page 0 / register 44, bit D4 is a sticky flag which is set when the headset insertion or removal event is
detected. These sticky flags are set by the event occurrence, and are reset only when read. This requires
polling page 0 / register 44. To avoid polling and the associated overhead, the TLV320AIC3111 also
provides an interrupt feature, whereby events can trigger the INT1 and/or INT2 interrupts. These interrupt
events can be routed to one of the digital output pins. See Section 5.6.6 for details.
The TLV320AIC3111 not only detects a headset insertion event, but also is able to distinguish between
the different headsets inserted, such as stereo headphones or cellular headphones. After the headsetdetection event, the user can read page 0 / register 67, bits D6–D5 to determine the type of headset
inserted.

from the AVDD supply.
5.6.6
Interrupts
Some specific events in the TLV320AIC3111 which may require host processor intervention, can be used
to trigger interrupts to the host processor. This avoids polling the status-flag registers continuously. The
TLV320AIC3111 has two defined interrupts, INT1 and INT2, that can be configured by programming
page 0 / register 48 and page 0 / register 49. A user can configure interrupts INT1 and INT2 to be
triggered by one or many events, such as:
• Headset detection
• Button press
• DAC DRC signal exceeding threshold
• Noise detected by AGC
• Overcurrent condition in headphone drivers/speaker drivers
• Data overflow in ADC and DAC processing blocks and filters
• DC measurement data available

Each of these INT1 and INT2 interrupts can be routed to output pins GPIO1 or DOUT. These interrupt
signals can either be configured as a single pulse or a series of pulses by programming page 0 /
register 48, bit D0 and page 0 / register 49, bit D0. If the user configures the interrupts as a series of
pulses, the events trigger the start of pulses that stop when the flag registers in page 0 / registers 44, 45,
and 50 are read by the user to determine the cause of the interrupt.
5.6.7
Key-Click Functionality With Beep Generator (PRB_P25)
A special algorithm has been included in the digital signal processing block PRB_P25 for generating a
digital sine-wave signal that is sent to the DAC. This functionality is intended for generating key-click
sounds for user feedback. The sine-wave generator is very flexible (see Table 5-36) and is completely
register programmable. Programming page 0 / register 71 through page 0 / register 79 (8 bits each)
completely controls the functionality of this generator and allows for differentiating sounds.
The two registers used for programming the 16-bit sine-wave coefficient are page 0 / register 76 and
page 0 / register 77. The two registers used for programming the 16-bit cosine-wave coefficient are
page 0 / register 78 and page 0 / register 79. This coefficient resolution allows virtually any frequency of
sine wave in the audio band to be generated, up to fS/2.
The three registers used to control the length of the sine-burst waveform are page 0 / register 73 through
page 0 / register 75. The resolution (bit) in the registers of the sine-burst length is one sample time, so this
allows great control on the overall time of the sine-burst waveform. This 24-bit length timer supports
16,777,215 sample times. (For example, if fS is set at 48 kHz, and the register value equals 96,000d
(01 7700h), then the sine burst lasts exactly 2 seconds.) The default settings for the tone generator, based
on using a sample rate of 48 kHz, are 1-kHz (approximately) sine wave, with a sine-burst length of five
cycles (5 ms).

These are the default settings.
Two registers are used to control the left sine-wave volume and the right sine-wave volume independently.
The 6-bit digital volume control used allows level control of 2 dB to –61 dB in 1-dB steps. The left-channel
volume is controlled by writing to page 0 / register 71, bits D5–D0. The right-channel volume is controlled
by writing to page 0, register 72, bits D5–D0. A master volume control that controls the left and right
channels of the beep generator can be set up by writing to page 0 / register 72, bits D7–D6. The default
volume control setting is 2 dB, which provides the maximum tone-generator output level.
For generating other tones, the three tone-generator coefficients can be found by running the following
script using MATLAB™ :
Sine = dec2hex(round(sin(2*pi*Fin/Fs)*2^15)) Cosine =
dec2hex(round(cos(2*pi*Fin/Fs)*2^15)) Beep Length =
dec2hex(floor(Fs*Cycle/Fin))

2. For the sine and cosine values, if the number of bits is less than the full 16-bit value, then the unused

3. For the beep-length values, if number of bits is less than the full 24-bit value, then the unused MSBs
must be written as 0s.
Following the beep-volume control is a digital mixer that mixes in a playback data stream whose level has
already been set by the DAC volume control. Therefore, once the key-click volume level is set, the keyclick volume is not affected by the DAC volume control, which is the main control available to the end
user. This functionality is shown in Figure 1-1.
Following the DAC, the signal can be further scaled by the analog output volume control and poweramplifier level control.
The beep generator is used for the key-click function. A single beep is generated by writing to page 0 /
register 71, bit D7. After the programmed beep length has finished, register 71, bit D7 is reset back to
zero.
5.6.8
Programming DAC Digital Filter Coefficients
The digital filter coefficients must be programmed through the I2C interface. All digital filtering for the DAC
signal path must be loaded into the RAM before the DAC is powered on. (Note that default ALLPASS filter
coefficients for programmable biquads are located in boot ROM. The boot ROM automatically loads the
default values into the RAM following a hardware reset (toggling the RESET pin) or after a software reset.
After resetting the device, loading boot ROM coefficients into the digital filters requires 100 μs of
programming time. During this time, reading or writing to page 8 through page 15 for updating DAC filter
coefficient values is not permitted. (The DAC should not be powered up until after all of the DAC
configurations have been done by the system microprocessor.)
5.6.9
Updating DAC Digital Filter Coefficients During PLAY
When it is required to update the DAC digital filter coefficients or beep generator during play, care must be
taken to avoid click and pop noise or even a possible oscillation noise. These artifacts can occur if the
DAC coefficients are updated without following the proper update sequence. The correct sequence is
shown in Figure 5-35. The values for times listed in Figure 5-35 are conservative and should be used for
software purposes.
There is also an adaptive mode, in which DAC coefficients can be updated while the DAC is on. For
details, see Section 5.6.1.3.

5.6.10 Digital Mixing and Routing
The TLV320AIC3111 has four digital mixing blocks. Each mixer can provide either mixing or multiplexing
of the digital audio data. This arrangement of digital mixers allows independent volume control for both the
playback data and the key-click sound. The first set of mixers can be used to make monaural signals from
left and right audio data, or they can even be used to swap channels to the DAC. This function is
accomplished by selecting left audio data for the right DAC input, and right data for the left DAC input. The
second set of mixers provides mixing of the audio data stream and the key-click sound. The digital routing
can be configured by writing to page 0 / register 63, bits D5–D4 for the left channel and bits D3–D2 for the
right channel.
Because the key-click function uses the digital signal processing block, the CODEC_CLKIN, DAC, analog
volume control, and output driver must be powered on for the key-click sound to occur.

5.6.11 Analog Audio Routing
The TLV320AIC3111 has the capability to route the DAC output to either the headphone or the speaker
output. If desirable, both output drivers can be operated at the same time while playing at different volume
levels. The TLV320AIC3111 provides various digital routing capabilities, allowing digital mixing or even
channel swapping in the digital domain. All analog outputs other than the selected ones can be powered
down for optimal power consumption.
5.6.11.1 Analog Output Volume Control
The output volume control can be used to fine-tune the level of the mixer amplifier signal supplied to the
headphone driver or the speaker driver. This architecture supports separate and concurrent volume levels
for each of the four output drivers. This volume control can also be used as part of the output pop-noise
reduction scheme. This feature is available even if the ADC and DAC are powered down.
5.6.11.2 Headphone Analog Output Volume Control
For the headphone outputs, the analog volume control has a range from 0 dB to –78 dB in 0.5-dB steps
for most of the useful range, which is shown in Table 5-38. To mute the headphone output, use register
value 0x7F. This volume control includes soft-stepping logic. Routing the left-channel DAC output signal to
the left-channel analog volume control is done by writing to page 1 / register 35, bit D6. Routing the rightchannel DAC output signal to the right-channel analog volume control is done by writing to page 1 /
register 35, bit D2.
Changing the left-channel analog volume for the headphone is controlled by writing to page 1 / register 36,
bits D6–D0. Changing the right-channel analog volume for the headphone is controlled by writing to
page 1 / register 37, bits D6–D0. Routing the signal from the output of the left-channel analog volume
control to the input of the left-channel headphone power amplifier is done by writing to page 1 /
register 36, bit D7. Routing the signal from the output of the right-channel analog volume control to the
input of the right-channel headphone power amplifier is done by writing to page 1 / register 37, bit D7.
The analog volume-control soft-stepping time is based on the setting in page 0 / register 63, bits D1–D0.

For the speaker outputs, the analog volume control has a range from 0 dB to –78 dB in 0.5-dB steps for
most of the useful range plus mute, as seen in Table 5-38. To mute the Class-D amplifier channel, use
register value 0x7F. The implementation includes soft-stepping logic.
Routing the left-channel DAC output signal to the left-channel analog volume control is done by writing to
page 1 / register 35, bit D6. Routing the right-channel DAC output signal to the right-channel analog
volume control is done by writing to page 1 / register 35, bit D2. Changing the left-channel analog volume
for the speaker is controlled by writing to page 1 / register 38, bits D6–D0. Changing the right-channel
analog volume for the speaker is controlled by writing to page 1 / register 39, bits D6–D0.
Routing the signal from the output of the left-channel analog volume control to the input of the left-channel
speaker amplifier is done by writing to page 1 / register 38, bit D7. Routing the signal from the output of
the right-channel analog volume control to the input of the right-channel speaker amplifier is done by
writing to page 1 / register 39, bit D7.
The analog volume-control soft-stepping time is based on the setting in page 0 / register 63, bits D1–D0.

5.6.12 Analog Outputs
Various analog routings are supported for playback. All the options can be conveniently viewed on the
functional block diagram, Figure 1-1.
5.6.12.1 Headphone Drivers
The TLV320AIC3111 features a stereo headphone driver (HPL and HPR) that can deliver up to 30 mW
per channel, at 3.3-V supply voltage, into a 16-Ω load. The headphones are used in a single-ended
configuration where an ac-coupling capacitor (dc-blocking) is connected between the device output pins
and the headphones. The headphone driver also supports 32-Ω and 10-kΩ loads without changing any
control register settings.
The headphone drivers can be configured to optimize the power consumption in the lineout-drive mode by
writing 11 to page 1 / register 44, bits D2–D1.
The output common mode of the headphone/lineout drivers can be programmed to 1.35 V, 1.5 V, 1.65 V,
or 1.8 V by setting page 1 / register 31, bits D4–D3. The common-mode voltage should be set ≤ AVDD/2.
The left headphone driver can be powered on by writing to page 1 / register 31, bit D7. The right
headphone driver can be powered on by writing to page 1 / register 31, bit D6. The left-output driver gain
can be controlled by writing to page 1 / register 40, bits D6–D3, and it can be muted by writing to page 1 /
register 40, bit D2. The right-output driver gain can be controlled by writing to page 1 / register 41,
bits D6–D3, and it can be muted by writing to page 1 / register 41, bit D2.
The TLV320AIC3111 has a short-circuit protection feature for the headphone drivers, which is always
enabled to provide protection. The output condition of the headphone driver during short circuit can be
programmed by writing to page 1 / register 31, bit D1. If D1 = 0 when a short circuit is detected, the device
limits the maximum current to the load. If D1 = 1 when a short circuit is detected, the device powers down
the output driver. The default condition for headphones is the current-limiting mode. In case of a short
circuit on either channel, the output is disabled and a status flag is provided as read-only bits on page 1 /
register 31, bit D0. If shutdown mode is enabled, then as soon as the short circuit is detected, page 1 /
register 31, bit D7 (for HPL) and/or page 1 / register 31, bit D6 (for HPR) clears automatically. Next, the
device requires a reset to re-enable the output stage. Resetting can be done in two ways. First, the device
master reset can be used, which requires either toggling the RESET pin or using the software reset. If
master reset is used, it resets all of the registers. Second, a dedicated headphone power-stage reset can
also be used to re-enable the output stage, and that keeps all of the other device settings. The headphone
power stage reset is done by setting page 1 / register 31, bit D7 for HPL and by setting page 1 /
register 31, bit D6 for HPR. If the fault condition has been removed, then the device returns to normal
operation. If the fault is still present, then another shutdown occurs. Repeated resetting (more than three
times) is not recommended, as this could lead to overheating.
5.6.12.2 Speaker Drivers
The TLV320AIC3111 has an integrated class-D stereo speaker driver (SPLP/SPLM and SPRP/SPRM)
capable of driving an 8-Ω differential load. The speaker driver can be powered directly from the battery
supply (2.7 V to 5.5 V) on the SPLVDD and SPRVDD pins; however, the voltage (including spike voltage)
must be limited below the absolute-maximum voltage of 6 V.
The speaker driver is capable of supplying 400 mW per channel with a 3.6-V power supply. Through the
use of digital mixing, the device can connect one or both digital audio playback data channels to either
speaker driver; this also allows digital channel swapping if needed.
The left class-D speaker driver can be powered on by writing to page 1 / register 32, bit D7. The right
class-D speaker driver can be powered on by writing to page 1 / register 32, bit D6. The left-output driver
gain can be controlled by writing to page 1 / register 42, bits D4–D3, and it can be muted by writing to
page 1 / register 42, bit D2. The right-output driver gain can be controlled by writing to page 1 /
register 43, bits D4–D3, and it can be muted by writing to page 1 / register 43, bit D2.

SLAS644D – JULY 2009 – REVISED MAY 2012
The TLV320AIC3111 has a short-circuit protection feature for the speaker drivers that is always enabled
to provide protection. If the output is shorted, the output stage shuts down on the overcurrent condition.
(Current limiting is not an available option for the higher-current speaker driver output stage.) In case of a
short circuit on either channel, the output is disabled and a status flag is provided as a read-only bit on
page 1 / register 32, bit D0.
If shutdown occurs due to an overcurrent condition, then the device requires a reset to re-enable the
output stage. Resetting can be done in two ways. First, the device master reset can be used, which
requires either toggling the RESET pin or using the software reset. If master reset is used, it resets all of
the registers. Second, a dedicated speaker power-stage reset can be used that keeps all of the other
device settings. The speaker power-stage reset is done by setting page 1 / register 32, bit D7 for SPLP
and SPLM and by setting page 1 / register 32, bit D6 for SPRP and SPRM. If the fault condition has been
removed, then the device returns to normal operation. If the fault is still present, then another shutdown
occurs. Repeated resetting (more than three times) is not recommended, as this could lead to
overheating.
To minimize battery current leakage, the SPLVDD and SPRVDD voltage levels should not be less
than the AVDD voltage level.
The TLV320AIC3111 has a thermal protection (OTP) feature for the speaker drivers which is always
enabled to provide protection. If the device is overheated, then the output stops switching. When the
device cools down, the device resumes switching. An overtemperature status flag is provided as a readonly bit on page 0 / register 3, bit D1. The OTP feature is for self-protection of the device. If die
temperature can be controlled at the system/board level, then overtemperature does not occur.
5.6.13 Audio Output-Stage Power Configurations
After the device has been configured (following a RESET) and the circuitry has been powered up, the
audio output stage can be powered up and powered down by register control.
These functions soft-start automatically. By using these register controls, it is possible to turn all four
stages on at the same time without turning two of them off.

CLOCK Generation and PLL
The TLV320AIC3111 supports a wide range of options for generating clocks for the ADC and DAC
sections as well as interface and other control blocks as shown in Figure 5-36. The clocks for the ADC
and DAC require a source reference clock. This clock can be provided on variety of device pins, such as
the MCLK, BCLK, or GPIO1 pins. The source reference clock for the codec can be chosen by
programming the CODEC_CLKIN value on page 0 / register 4, bits D1–D0. CODEC_CLKIN can then be
routed through highly-flexible clock dividers shown in Figure 5-36 to generate the various clocks required

for the ADC, DAC, and miniDSP sections. In the event that the desired audio or miniDSP clocks cannot be
generated from the reference clocks on MCLK, BCLK, or GPIO1, the TLV320AIC3111 also provides the
option of using the on-chip PLL which supports a wide range of fractional multiplication values to generate
the required clocks. Starting from CODEC_CLKIN, the TLV320AIC3111 provides several programmable

The DAC modulator is clocked by DAC_MOD_CLK. For proper power-up operation of the DAC channel,
DAC_MOD_CLK must be enabled by configuring the NDAC and MDAC clock dividers (page 0 /
register 11, bit D7 = 1 and page 0 / register 12, bit D7 = 1). When the DAC channel is powered down, the
device internally initiates a power-down sequence for proper shutdown. During this shutdown sequence,
the NDAC and MDAC dividers must not be powered down, or else a proper low-power shutdown may not
take place. The user can read back the power-status flag at page 0 / register 37, bit D7 and page 0 /
register 37, bit D3. When both the flags indicate power-down, the MDAC divider may be powered down,
followed by the NDAC divider. Note that when the ADC clock dividers are powered down, the ADC clock
is derived from the DAC clocks.
The ADC modulator is clocked by ADC_MOD_CLK. For proper power-up of the ADC channel, these
clocks are enabled by the NADC and MADC clock dividers (page 0 / register 18, bit D7 = 1 and page 0 /
register 19, bit D7 = 1). When the ADC channel is powered down, the device internally initiates a powerdown sequence for proper shutdown. During this shutdown sequence, the NADC and MADC dividers must
not be powered down, or else a proper low-power shutdown may not take place. The user can read back
the power-status flag from page 0 / register 36, bit D6. When this flag indicates power down, the MADC
divider may be powered down, followed by NADC divider.
When ADC_CLK (ADC DSP clock) is derived from the NDAC divider output, the NDAC must be kept
powered up until the power-down status flags for ADC do not indicate power down. When the input to the
AOSR clock divider is derived from DAC_MOD_CLK, then MDAC must be powered up when ADC_fS is
needed (i.e., when WCLK is generated by the TLV320AIC3111 or AGC is enabled) and can be powered
down only after the ADC power-down flags indicate power-down status.
In general, for proper operation, all the root clock dividers should be powered down only after the child
clock dividers have been powered down.
The TLV320AIC3111 also has options for routing some of the internal clocks to the output pins of the
device to be used as general-purpose clocks in the system. The feature is shown in Figure 5-38.

In the mode when the TLV320AIC3111 is configured to drive the BCLK pin (page 0 / register 27,
bit D3 = 1), it can be driven as the divided value of BDIV_CLKIN. The division value can be programmed
in page 0 / register 30, bits D6–D0 from 1 to 128. BDIV_CLKIN can itself be configured to be one of
DAC_CLK (DAC DSP clock), DAC_MOD_CLK, ADC_CLK (ADC DSP clock) or ADC_MOD_CLK by
configuring the BDIV_CLKIN multiplexer in page 0 / register 29, bits D1–D0. Additionally, a generalpurpose clock can be driven out on either GPIO1 or DOUT.
This clock can be a divided-down version of CDIV_CLKIN. The value of this clock divider can be
programmed from 1 to 128 by writing to page 0 / register 26, bits D6–D0. CDIV_CLKIN can itself be

PLL
For lower power consumption, it is best to derive the internal audio processing clocks using the simple
dividers. When the input MCLK or other source clock is not an integer multiple of the audio processing
clocks then it is necessary to use the on-board PLL. The TLV320AIC3111 fractional PLL can be used to
generate an internal master clock used to produce the processing clocks needed by the ADC, DAC, and
miniDSP. The programmability of this PLL allows operation from a wide variety of clocks that may be
available in the system.
The PLL input supports clocks varying from 512 kHz to 20 MHz and is register-programmable to enable
generation of the required sampling rates with fine resolution. The PLL can be turned on by writing to
page 0 / register 5, bit D7. When the PLL is enabled, the PLL output clock, PLL_CLK, is given by the
following equation:
PLL_CLKIN ´ R ´ J.D
PLL_CLK =
P
(9)
where
R = 1, 2, 3, ..., 16 (page 0 / register 5, default value = 1)
J = 1, 2,3, … , 63, (page 0 / register 6, default value = 4)
D = 0, 1, 2, …, 9999 (page 0 / register 7 and page 0 / register 8, default value = 0)
P = 1, 2, 3, …, 8 (page 0 / register 5, default value = 1)
The PLL can be turned on via page 0 / register 5, bit D7. The variable P can be programmed via page 0 /
register 5, bits D6–D4. The variable R can be programmed via page 0 / register 5, bits D3–D0. The
variable J can be programmed via page 0 / register 6, bits D5–D0. The variable D is 14 bits and is
programmed into two registers. The MSB portion can be programmed via page 0 / register 7, bits D5–D0,
and the LSB portion is programmed via page 0 / register 8, bits D7–D0. For proper update of the D divider

The PLL can be powered up independently from the ADC and DAC blocks, and can also be used as a
general-purpose PLL by routing its output to the GPIO output. After powering up the PLL, PLL_CLK is
available typically after 10 ms.
The clocks for the codec and various signal processing blocks, CODEC_CLKIN, can be generated from
the MCLK input, BCLK input, GPIO input, or PLL_CLK (page 0 / register 4, bits D1–D0).
If CODEC_CLKIN is derived from the PLL, then the PLL must be powered up first and powered down last.
Table 5-42 lists several example cases of typical PLL_CLKIN rates and how to program the PLL to
achieve a sample rate fS of either 44.1 kHz or 48 kHz.

Timer
The internal clock runs nominally at 8.2 MHz. This is used for various internal timing intervals, de-bounce
logic, and interrupts. The MCLK divider must be set in such a way that the divider output is approximately
1 MHz for the timers to be closer to the programmed value.

Digital Audio and Control Interface
Digital Audio Interface
Audio data is transferred between the host processor and the TLV320AIC3111 via the digital audio data
serial interface, or audio bus. The audio bus on this device is very flexible, including left- or right-justified
data options, support for I2S or PCM protocols, programmable data length options, a TDM mode for
multichannel operation, very flexible master/slave configurability for each bus-clock line, and the ability to
communicate with multiple devices within a system directly.
The audio bus of the TLV320AIC3111 can be configured for left- or right-justified, I2S, DSP, or TDM
modes of operation, where communication with standard telephony PCM interfaces is supported within the
TDM mode. These modes are all MSB-first, with data width programmable as 16, 20, 24, or 32 bits by
configuring page 0 / register 27, bits D5–D4. In addition, the word clock and bit clock can be
independently configured in either master or slave mode, for flexible connectivity to a wide variety of
processors. The word clock is used to define the beginning of a frame, and may be programmed as either
a pulse or a square-wave signal. The frequency of this clock corresponds to the maximum of the selected
ADC and DAC sampling frequencies.
The bit clock is used to clock in and clock out the digital audio data across the serial bus. When in master
mode, this signal can be programmed to generate variable clock pulses by controlling the bit-clock divider
in page 0 / register 30 (see Figure 5-36). The number of bit-clock pulses in a frame may need adjustment
to accommodate various word lengths as well as to support the case when multiple TLV320AIC3111s may
share the same audio bus.
The TLV320AIC3111 also includes a feature to offset the position of start of data transfer with respect to
the word clock. This offset can be controlled in terms of number of bit-clocks and can be programmed in
page 0 / register 28.
The TLV320AIC3111 also has the feature of inverting the polarity of the bit clock used for transferring the
audio data as compared to the default clock polarity used. This feature can be used independently of the
mode of audio interface chosen. This can be configured via page 0 / register 29, bit D3.

The TLV320AIC3111 further includes programmability (page 0 / register 27, bit D0) to place the DOUT line
in the high-impedance state during all bit clocks when valid data is not being sent. By combining this
capability with the ability to program at what bit clock in a frame the audio data begins, time-division
multiplexing (TDM) can be accomplished, enabling the use of multiple codecs on a single audio serial data
bus. When the audio serial data bus is powered down while configured in master mode, the pins
associated with the interface are put into a high-impedance output condition. Also, DOUT control on
page 0 / register 53, bit D4 allows the bus-keeper feature to be enabled/disabled. When enabled, the last
valid data on DOUT is held (weakly driven) during the non-data time. When disabled, DOUT is placed in a
high-impeance state when page 0 / register 27, bit D0 is enabled (1).
By default, when the word clocks and bit clocks are generated by the TLV320AIC3111, these clocks are
active only when the codecs (ADC, DAC or both) are powered up within the device. This is done to save
power. However, it also supports a feature when both the word clocks and bit clocks can be active even
when the codec in the device is powered down. This is useful when using the TDM mode with multiple
codecs on the same bus, or when word clocks or bit clocks are used in the system as general-purpose
clocks.
5.9.1.1
Right-Justified Mode
The audio interface of the TLV320AIC3111 can be put into the right-justified mode by programming
page 0 / register 27, bits D7–D6 = 10. In right-justified mode, the LSB of the left channel is valid on the
rising edge of the bit clock preceding the falling edge of the word clock. Similarly, the LSB of the right
channel is valid on the rising edge of the bit clock preceding the rising edge of the word clock.

The audio interface of the TLV320AIC3111 can be put into left-justified mode by programming page 0 /

of the bit clock following the falling edge of the word clock. Similarly, the MSB of the left channel is valid
on the rising edge of the bit clock following the rising edge of the word clock.

The audio serial interface on the TLV320AIC3111 has extensive I/O control to allow communication with
two independent processors for audio data. The processors can communicate with the device one at a
time. This feature is enabled by register programming of the various pin selections. Table 5-43 shows the
primary and secondary audio interface selection and registers. Table 5-44 shows the selection criteria for
generating ADC_WCLK. Figure 5-51 is a high-level diagram showing the general signal flow and

SLAS644D – JULY 2009 – REVISED MAY 2012
Control Interface
The TLV320AIC3111 control interface supports the I2C communication protocol.
5.9.3.1
I2C Control Mode
The TLV320AIC3111 supports the I2C control protocol, and responds to the I2C address of 0011 000. I2C
is a two-wire, open-drain interface supporting multiple devices and masters on a single bus. Devices on
the I2C bus only drive the bus lines LOW by connecting them to ground; they never drive the bus lines
HIGH. Instead, the bus wires are pulled HIGH by pullup resistors, so the bus wires are HIGH when no
device is driving them LOW. This way, two devices cannot conflict; if two devices drive the bus
simultaneously, there is no driver contention.
Communication on the I2C bus always takes place between two devices, one acting as the master and the
other acting as the slave. Both masters and slaves can read and write, but slaves can only do so under
the direction of the master. Some I2C devices can act as masters or slaves, but the TLV320AIC3111 can
only act as a slave device.
An I2C bus consists of two lines, SDA and SCL. SDA carries data, and the SCL signal provides the clock.
All data is transmitted across the I2C bus in groups of eight bits. To send a bit on the I2C bus, the SDA line
is driven to the appropriate level while SCL is LOW (a LOW on SDA indicates the bit is zero, while a HIGH
indicates the bit is one).
Once the SDA line has settled, the SCL line is brought HIGH, then LOW. This pulse on the SCL line
clocks the SDA bit into the receiver shift register.
The I2C bus is bidirectional: the SDA line is used both for transmitting and receiving data. When a master
reads from a slave, the slave drives the data line; when a master sends to a slave, the master drives the
data line.
Most of the time the bus is idle, no communication is taking place, and both lines are HIGH. When
communication is taking place, the bus is active. Only master devices can start communication on the bus.
Normally, the data line is only allowed to change state while the clock line is LOW. If the data line changes
state while the clock line is HIGH, it is either a START condition or its counterpart, a STOP condition. A
START condition is when the clock line is HIGH and the data line goes from HIGH to LOW. A STOP
condition is when the clock line is HIGH and the data line goes from LOW to HIGH.
After the master issues a START condition, it sends a byte that selects the slave device for
communication. This byte is called the address byte. Each device on an I2C bus has a unique 7-bit
address to which it responds. (Slaves can also have 10-bit addresses; see the I2C specification for
details.) The master sends an address in the address byte, together with a bit that indicates whether it is
to read from or write to the slave device.
Every byte transmitted on the I2C bus, whether it is address or data, is acknowledged with an
acknowledge bit. When a master has finished sending a byte (eight data bits) to a slave, it stops driving
SDA and waits for the slave to acknowledge the byte. The slave acknowledges the byte by pulling SDA
LOW. The master then sends a clock pulse to clock the acknowledge bit. Similarly, when a master has
finished reading a byte, it pulls SDA LOW to acknowledge this to the slave. It then sends a clock pulse to
clock the bit. (Remember that the master always drives the clock line.)
A not-acknowledge is performed by simply leaving SDA HIGH during an acknowledge cycle. If a device is
not present on the bus, and the master attempts to address it, it receives a not-acknowledge because no
device is present at that address to pull the line LOW.
When a master has finished communicating with a slave, it may issue a STOP condition. When a STOP
condition is issued, the bus becomes idle again. A master may also issue another START condition. When
a START condition is issued while the bus is active, it is called a repeated START condition.
The TLV320AIC3111 can also respond to and acknowledge a general call, which consists of the master
issuing a command with a slave address byte of 00h. This feature is disabled by default, but can be
enabled via page 0 / register 34, bit D5.

Figure 5-53. I2C Read
In the case of an I2C register write, if the master does not issue a STOP condition, then the device enters
auto-increment mode. So in the next eight clocks, the data on SDA is treated as data for the next
incremental register.
Similarly, in the case of an I2C register read, after the device has sent out the 8-bit data from the
addressed register, if the master issues a ACKNOWLEDGE, the slave takes over control of the SDA bus
and transmits for the next eight clocks the data of the next incremental register.

6 REGISTER MAP
6.1
TLV320AIC3111 Register Map
All features on this device are addressed using the I2C bus. All of the writable registers can be read back.
However, some registers contain status information or data, and are available for reading only.
The TLV320AIC3111 contains several pages of 8-bit registers, and each page can contain up to 128
registers. The register pages are divided up based on functional blocks for this device. The pages defined
for the TLV320AIC3111 are 0, 1, 3, 4–5 (ADC coefficient pages), 8–15 (DAC coefficient pages), 32–43
(ADC IRAM pages), and 64–95 (DAC IRAM pages). Page 0 is the default home page after RESET. Page
control is done by writing a new page value into register 0 of the current page.
The control registers for the TLV320AIC3111 are described in detail as follows. All registers are 8 bits in
width, with D7 referring to the most-significant bit of each register, and D0 referring to the least-significant
bit.
Pages 0, 1, 3, 4–5, 8–15, 32–43, and 64–95 are available for use; however, all other pages and registers
are reserved. Do not read from or write to reserved pages and registers. Also, do not write other than the
reset values for the reserved bits and read-only bits of non-reserved registers; otherwise, device
functionality failure can occur.

External clock is used only to control the delay programmed between the conversions and not used for doing the actual conversion. This
feature is provided in case a more accurate delay is desired since the internal oscillator frequency varies from device to device.

The remaining page 4 registers are either reserved registers or are used for setting coefficients for the
various filters in the TLV320AIC3111. Reserved registers should not be written to.
The filter coefficient registers are arranged in pairs, with two adjacent 8-bit registers containing the 16-bit
coefficient for a single filter. The 16-bit integer contained in the MSB and LSB registers for a coefficient
are interpreted as a 2s-complement integer, with possible values ranging from –32,768 to 32,767. When
programming any coefficient value for a filter, the MSB register should always be written first, immediately
followed by the LSB register. Even if only the MSB or LSB portion of the coefficient changes, both
registers should be written in this sequence. Table 6-2 is a list of the page-4 registers, excepting the
previously described register 0.

The remaining page-8 registers are either reserved registers or are used for setting coefficients for the
various filters in the TLV320AIC3111. Reserved registers should not be written to.
The filter coefficient registers are arranged in pairs, with two adjacent 8-bit registers containing the 16-bit
coefficient for a single filter. The 16-bit integer contained in the MSB and LSB registers for a coefficient
are interpreted as a 2s-complement integer, with possible values ranging from –32,768 to 32,767. When
programming any coefficient value for a filter, the MSB register should always be written first, immediately
followed by the LSB register. Even if only the MSB or LSB portion of the coefficient changes, both
registers should be written in this sequence. Table 6-4 is a list of the page-8 registers, excepting the
previously described register 0.

The remaining page-9 registers are either reserved registers or are used for setting coefficients for the
various filters in the TLV320AIC3111. Reserved registers should not be written to.
The filter-coefficient registers are arranged in pairs, with two adjacent 8-bit registers containing the 16-bit
coefficient for a single filter. The 16-bit integer contained in the MSB and LSB registers for a coefficient
are interpreted as a 2s-complement integer, with possible values ranging from –32,768 to 32,767. When
programming any coefficient value for a filter, the MSB register should always be written first, immediately
followed by the LSB register. Even if only the MSB or LSB portion of the coefficient changes, both
registers should be written in this sequence. Table 6-5 is a list of the page-9 registers, excepting the
previously described register 0.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3)
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4)
There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5)
Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
