EVM Overview
•Full-featured evaluation board for the TLV320AIC3007 2-channel audio codec with integrated Class-Damplifier.
•Modular design for use with a variety of digital signal processor (DSP) and microcontroller interfaceboards.
•USB connection to PC provides power, control, and streaming audio data for easy evaluation.
•Onboard microphone for ADC evaluation
•Connection points for external control and digital audio signals for quick connection to othercircuits/input devices.
The TLV320AIC3007EVM-K is a complete evaluation kit, which includes a universal serial bus(USB)-based motherboard and evaluation software for use with a personal computer (PC) running theMicrosoft Windows™ operating system (Win2000 or XP).
The TLV320AIC3007EVM is in the Texas Instruments modular EVM form factor, which allows directevaluation of the device performance and operating characteristics, and eases software development andsystem prototyping. This EVM is compatible with the 5-6K Interface Evaluation Module (SLAU104 ) and theHPA-MCUINTERFACE (SLAU106 ) from Texas Instruments and additional third-party boards whichsupports the TI Modular EVM format.
The TLV320AIC3007EVM-K is a complete evaluation/demonstration kit, which includes a USB-basedmotherboard called the USB-MODEVM Interface board and evaluation software for use with a PC runningthe Microsoft Windows operating systems.
The USB connection from the PC provides power, control, and streaming audio data to the EVM forreduced setup and configuration. The EVM also allows external control signals, audio data, and power foradvanced operation, which allows prototyping and connection to the rest of the evaluation/developmentsystem.
This section provides information on the analog input and output, digital control, power, and generalconnection of the TLV320AIC3007EVM.
The TLV320AIC3007EVM-K consists of two separate circuit boards, the USB-MODEVM and theTLV320AIC3007EVM. The USB-MODEVM is built around a TAS1020B streaming audio USB controllerwith an 8051-based core.
The simple diagram of Figure 1 shows how the TLV320AIC3007EVM is connected to the USB-MODEVM.The USB-MODEVM Interface board is intended to be used in USB mode, whereas control of the installedEVM is accomplished using the onboard USB controller device. Provision is made, however, for driving allthe data buses (I

C, I

S, etc.) externally. The source of these signals is controlled by SW2 on theUSB-MODEVM. See Table 1 for details on the switch settings.
