USB
The serial interface clocks and data are provided from the USB interface. The sampling rate and format
are determined by the USB audio class driver on the operating system. The default settings for the USB
audio interface are 32-bit frame size, 48-kHz sampling rate, BCLK and FSYNC ratio is 256, and the format
is time-division multiplexing (TDM).
The AC-MB is detected by the OS as an audio device with the name TI USB Audio UAC2.0. Figure 2
shows the AC-MB audio setting for the USB mode of operation.

2.1.1.2
Optical or Auxilary Analog Audio Input
Serial interface signals are provided from the PCM9211 digital transceiver, which is capable of sending
digital data to the EVB from an analog input or optical input. Meanwhile, the data from the EVB can be
streamed through the optical output. Figure 3 shows the AC-MB audio setting for the optical and analog
mode of operation.
ON

Figure 3. AC-MB Optical or Auxiliary Analog Audio Setting
The optical output of the AC-MB streams the data captured on the EVM with the format determined by the
input source used. When there is an optical input connected, the LOCK LED must be ON, and the
PCM9211 streams the audio serial interface clocks with the format determined by the optical input frame.
The digital data from the optical input is streamed to the evaluation module. If the optical input is not
connected, the PCM9211 captures the input signal provided through the analog input, and streams the
signal to the evaluation module. This feature can be useful when a digital input DAC is connected to the
AC-MB, providing an analog input for quick evaluation. In Auxiliary Analog Audio mode the audio serial
interface format is fixed to a 24-bit, 48-kHz, I2S mode.

In this mode, the audio serial interface clocks for the evaluation board are provided through connector J7
from an external source. This architecture allows the use of an external system to communicate with the
evaluation board, such as a different host processor or test equipment (for instance, Audio Precision
PSIA). The clocks generated from the USB interface and PCM9211 are isolated with this setting. Figure 4
shows the AC-MB audio setting for the external mode of operation.

AC-MB Power Supply
The complete EVM system is powered from a single 5-V power supply. However, the motherboard has
different low-dropout regulators (LDOs) integrated that provide the required power supplies to the different
blocks of the board. Figure 6 shows a block diagram depicting the power structure of the AC-MB.
To EVM
Figure 6. Power-Supply Distribution of the AC-MB
The AC-MB can be powered from the host computer by using the USB 5-V power supply (VBUS) by
shorting header J5, USB POWER. Additionally, the AC-MB can be powered from an external power
supply connected to terminal J4, EXTERNAL POWER. Header J5 must be open for external supply
operation. The IOVDD voltage for the digital signals that is provided to the evaluation module is generated
on the motherboard from the main power supply (USB or external). The voltage levels available are 1.8 V
and 3.3 V, and can be selected via the J3 header IOVDD. For 1.8-V operation, short pins 2 and 3 of
header J3; for 3.3-V operation, short pins 1 and 2. When the motherboard is fully powered and the power
supplies from the onboard LDOs are correct, the green POWER LED (D3) turns ON. The USB READY
LED indicates that a successful USB communication is established between the AC-MB and the host
computer.

Onboard Microphone Input
For the onboard microphone input configuration (shown in Figure 9), the TLV320ADCx140 records the
audio captured from the microphones located on the bottom edge of the board. MICBIAS is used to power
the onboard microphone, so header J14 must be shorted. There must not be any connections to J1 during
onboard microphone use to preserve the performance of the microphone.
