EVM Overview

1 EVM Overview

1.1 Features

• Full-featured evaluation board for the TLV320AIC3106 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.

• On-board microphone for ADC evaluation

• Connection points for external control and digital audio signals for quick connection to other

circuits/input devices.

The TLV320AIC3106EVM-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 (Win2000 or XP).

1.2 Introduction

The TLV320AIC3106EVM is in 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 Evaluation Module (SLAU104) and the

HPA-MCUINTERFACE (SLAU106) from Texas Instruments and additional third-party boards which

support TI's Modular EVM format.

The TLV320AIC3106EVM-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 running the Microsoft Windows operating systems.

The TLV320AIC3105EVM-PDK is operational with one USB cable connection to a personal computer. The

USB connection provides power, control, and streaming audio data to the EVM for reduced setup and

configuration. The EVM also allows external control signals, audio data, and power for advanced

operation, which allows prototyping and connection 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 TLV320AIC3106EVM.

2.1 TLV320AIC3106EVM-PDK Block Diagram

The TLV320AIC3106EVM-PDK consists of two separate circuit boards, the USB-MODEVM and the

TLV320AIC3106EVM. 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 may be installed. The TLV320AIC3106EVM is one of the double-wide modular EVMs

that is designed to work with the USB-MODEVM.

The simple diagram below (Figure 1) shows the how the TLV320AIC3106EVM 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 (I

C, SPI™, I

S/AC97) externally. The source of these signals is

controlled by SW2 on the USB-MODEVM. Refer to Table 1 for details on the switch settings.

The USB-MODEVM has two EVM positions that allow for the connection of two small evaluation module

or one larger evaluation module. The TLV320AIC3106EVM is designed to fit over both of the smaller

evaluation module slots as shown below.
