EVM WARNINGS AND RESTRICTIONS
It is important to operate this EVM within the input voltage range of 3.3 V described in the EVM
User’s Guide.
Exceeding the specified input range may cause unexpected operation and/or irreversible
damage to the EVM. If there are questions concerning the input range, please contact a TI
field representative prior to connecting the input power.
Applying loads outside of the specified output range may result in unintended operation and/or
possible permanent damage to the EVM. Please consult the EVM User’s Guide prior to
connecting any load to the EVM output. If there is uncertainty as to the load specification,
please contact a TI field representative.
During normal operation, some circuit components may have case temperatures greater than
60°C. The EVM is designed to operate properly with certain components above 60°C as long
as the input and output ranges are maintained. These components include but are not limited
to linear regulators, switching transistors, pass transistors, and current sense resistors. These
types of devices can be identified using the EVM schematic located in the EVM User’s Guide.
When placing measurement probes near these devices during operation, please be aware
that these devices may be very warm to the touch.

Introduction
1.1 Introduction
This EVM and user’s guide supports the following devices:
TLV320AIC1103
TLV320AIC1109
TLV320AIC1110
These devices are voice-band audio processors, designed to perform
transmit-encoding analog-to-digital (A/D) conversion, receive-decoding
digital-to-analog (D/A) conversion, and transmit and receive filtering for
voice-band communications systems.
The EVM can operate with a DSP development platform to provide the
necessary power requirements and a convenient way to interface with TI’s
range of starter kits via the 80-pin expansion connector located on the DSK.
Alternatively, the EVM can operate without a DSP development platform. In
this case the user is responsible for providing a suitable interface to the host
system.
System-level features for the chip are managed via 2 jumpers. Register
programming is achieved via an I2C interface.
Interfacing with the analog I/O is accomplished via 3 screw terminals.

Description
2.1 Description
The digital signals required to operate this codec originate from the 40-pin
connector—J1. There are two methods to drive the digital interface:
Create a custom interface between the codec EVM and the host system.
Alternatively, if a TI DSP starter kit (DSK) is the host system, a development platform is available from TI. This platform provides the additional
functions that the codec requires in a convenient form factor.
2.2 Codec-to-Development Platform Interface
The EVM mates with TI’s DSP starter kit systems (DSKs) via the development
platform.
The development platform mates with the DSK, through which all the
necessary power is provided. RESET can be manually furnished to the EVM
via a switch on the development platform, or by the RESET signal on the DSK
via the development platform.
Figure 2 - 1. Development Platform Mechanical Interface
Development
Platform
AIC1103 /09 /10
DSK
Electrical interface to the development platform is via a 40-pin connector on
the TLV320AIC1103/1109/1110 EVM. The connector mates with the
development platform connector (Samtec part number, TSM-120-01-T-DV-P).
Consult Samtec at www.samtec.com or 1-800-SAMTEC-9 for more
information.
The pinout for the 40-pin connector is given in Table 2 - 1.

Jumper Options
The development platform supports a number of functions required by the
codecs:
Manual reset generation
Power options
Convenient mechanical interface to TI’s DSK
Refer to SLAU090 for details regarding the development platform.
2.3 Jumper Options
There are two jumpers on the EVM board that can be configured in various
ways, depending upon the user’s requirements. Their functions are briefly presented in the following tables.

2.3.2
PCM Interface
The PCM interface transmits and receives data at the PCMO (DOUT) and
PCMI (DIN) terminals respectively. The data is transmitted or received at the
PCMCLK (SCLK) speed once every PCMSYN cycle (FS). The PCMCLK can
be tied directly to a master 2.048 MHz clock (MCLK).

2.4 Analog Interface
To make it as easy as possible to connect to a wide range of input and output
devices, the analog interface features simple screw terminals—J2 and J3 for
microphone inputs, and J4 for earphone output.
