www.ti.com EVM Overview
1 EVM Overview
1.1 Features
The features of the TLV320AIC3101EVM include:
• Full-featured evaluation board for the TLV320AIC3101 stereo audio codec.
• Modular design for use with a variety of digital signal processor (DSP) and microcontroller interface
boards.
• USB connection to PC provides power, control, and streaming audio data for easy evaluation.
• An onboard microphone for ADC evaluation.
• Connection points for external control and digital audio signals for quick connection to other
circuits/input devices.
The TLV320AIC3101EVM-PDK is a complete evaluation kit, which includes a universal serial bus (USB)-
based motherboard and evaluation software for use with a personal computer running the Microsoft®
Windows®operating system (Windows 2000 or Windows XP).
1.2 Introduction
The TLV320AIC3101EVM uses the Texas Instruments modular EVM form factor, which allows direct
evaluation of the device performance and operating characteristics, and eases software development and
system prototyping. This EVM is compatible with the 5-6K Interface Board (SLAU104) and the HPA-MCU
Interface Board (SLAU106) from Texas Instruments and additional third-party boards which support TI's
modular EVM format.
The TLV320AIC3101EVM-PDK is a complete evaluation/demonstration kit, which includes a USB-based
motherboard called the USB-MODEVM Interface Board and evaluation software for use with a personal
computer (PC) running the Microsoft Windows operating systems.
The TLV320AIC3101EVM-PDK operates with one USB cable connecting to a PC. The USB connection
provides power, control, and streaming audio data to the EVM for reduced setup and configuration. The
EVM also allow external control signals, audio data, and power for advanced operation, which permits
prototyping and connecting to the rest of the development or system evaluation.
2 EVM Description and Basics
This section provides information on the analog input and output, digital control, power, and general
connection of the TLV320AIC3101EVM.
2.1 TLV320AIC3101EVM-PDK Block Diagram
The TLV320AIC3101EVM-PDK consists of two separate circuit boards, the USB-MODEVM and the
TLV320AIC3101EVM. The USB-MODEVM is built around a TAS1020B streaming audio USB controller
with an 8051-based core. The motherboard features two positions for modular EVMs, or one double-wide
serial modular EVM can be installed. The TLV320AIC3101EVM is one of the double-wide modular EVMs
that is designed to work with the USB-MODEVM.
The simple diagram of Figure 1 shows how the TLV320AIC3101EVM is connected to the USB-MODEVM.
The USB-MODEVM Interface Board is intended to be used in USB mode, where control of the installed
EVM is accomplished using the onboard USB controller device. Provision is made, however, for driving all
the data buses (I2C, SPI™, I2S/AC97) externally. The source of these signals is controlled by SW2 on the
USB-MODEVM. See Table 2 for details on the switch settings.
The USB-MODEVM has two EVM positions that allow for the connection of two small evaluation modules
or one larger evaluation module. The TLV320AIC3101EVM is designed to fit over both of the smaller
evaluation module slots as shown in Figure 1.

2.4 Digital Signal Connections
2.4.1 Digital Inputs and Outputs
The digital inputs and outputs of the EVM can be monitored through J4 and J5. If external signals need to
be connected to the EVM, digital inputs should be connected via J14 and J15 on the USB-MODEVM and
the SW2 switch should be changed accordingly (see Section 2.2.1). The connector details are available in
Section A.2.
2.4.2 Digital Controls
The digital control signals can be applied directly to J4 and J5 (top or bottom side). The modular
TLV320AIC3101EVM also can be connected directly to a DSP interface board, such as the 5-6K Interface
Board or the HPA-MCU Interface Board, or to the USB-MODEVM Interface Board if purchased as part of
the TLV320AIC3101EVM-PDK. See the product folders on the TI Web site for these evaluation modules
or the TLV320AIC3101 for a current list of compatible interface and/or accessory boards.
2.5 Power Connections
The TLV320AIC3101EVM can be powered independently when being used in stand-alone operation or by
the USB-MODEVM when it is plugged onto the motherboard.
2.5.1 Stand-Alone Operation
When used as a stand-alone EVM, power is applied to J3 directly; ensure that the supplies are referenced
to the appropriate grounds on that connector.
CAUTION
Verify that all power supplies are within the safe operating limits shown in the
TLV320AIC3101 data sheet (SLAS520) before applying power to the EVM.
J3 provides connection to the common power bus for the TLV320AIC3101EVM. Power is supplied on the
pins listed in Table 8.
The TLV320AIC3101EVM-PDK motherboard (the USB-MODEVM Interface board) supplies power to J3 of
the TLV320AIC3101EVM. Power for the motherboard is supplied either through its USB connection or via
terminal blocks on that board.

TLV320AIC3101EVM-PDK Setup and Installation www.ti.com
2.5.2 USB-MODEVM Operation
The USB-MODEVM Interface Board can be powered from several different sources:
• USB
• 6-Vdc to 10-Vdc ac/dc external wall supply (not included)
• Laboratory power supply
When powered from the USB connection, JMP6 should have a shunt from pins 1–2 (this is the default
factory configuration). When powered from 6 Vdc to 10 Vdc, either through the J8 terminal block or J9
barrel jack, JMP6 should have a shunt installed on pins 2–3. If power is applied in any of these ways,
onboard regulators generate the required supply voltages and no further power supplies are necessary.
If laboratory supplies are used to provide the individual voltages required by the USB-MODEVM Interface
Board, JMP6 should have no shunt installed. Voltages then are applied to J2 (+5 VA), J3 (+5 VD), J4
(+1.8 VD), and J5 (+3.3 VD). The +1.8 VD and +3.3 VD can also be generated on the board by the
onboard regulators from the +5-VD supply; to enable this configuration, the switches on SW1 need to be
set to enable the regulators by placing them in the ON position (lower position, looking at the board with
text reading right-side up). If +1.8 VD and +3.3 VD are supplied externally, disable the onboard regulators
by placing SW1 switches in the OFF position.
Each power supply voltage has an LED (D1-D7) that lights when the power supplies are active.
3 TLV320AIC3101EVM-PDK Setup and Installation
The following section provides information on using the TLV320AIC3101EVM-PDK, including setup,
program installation, and program usage.
NOTE: If using the EVM in stand-alone mode, the software should be installed per the following
procedure, but the hardware configuration may be different.
3.1 Software Installation
1. Locate the installation file on the CD-ROM included with the EVM or download the latest version of the
software located on the AIC3101 product page. If downloading the software from the TI Web site, an
option is available to allow the user to be notified when the software is updated.
2. Unzip the installation file by clicking on the self-extracting zip file.
3. Install the EVM software by double-clicking the Setup executable file and follow the directions. Users
may be prompted to restart their computers.
This should install all the TLV320AIC310x software and required drivers onto the PC.
3.2 EVM Connections
1. Ensure that the TLV320AIC3101EVM is installed on the USB-MODEVM Interface Board, aligning J1,
J2, J3, J4, and J5 with the corresponding connectors on the USB-MODEVM Interface Board.
2. Verify that the jumpers and switches are in their default conditions.
3. Attach a USB cable from the PC to the USB-MODEVM Interface Board. The default configuration
provides power, control signals, and streaming audio via the USB interface from the PC. On the USB-
MODEVM Interface Board, LEDs D3–6 should light to indicate that the power is being supplied from
the USB.
4. For the first connection, the PC should recognize new hardware and begin an initialization process.
The user may be prompted to identify the location of the drivers or allow the PC to automatically
search for them. Allow the automatic detection option.
5. Once the PC confirms that the hardware is operational, D2 on the USB-MODEVM Interface Board
should light to indicate that the firmware has been loaded and the EVM is ready for use. If the LED is
not lit, verify that the drivers were installed, unplug the USB cable, and restart the procedure at Step 3.
