The TLV320AIC3253EVM-K is operational with one USB cable connection to a PC. 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.

TLV320AIC3253EVM-K Block Diagram
The TLV320AIC3253EVM-K consists of two separate circuit boards, the USB-MODEVM and the
TLV320AIC3253EVM. The USB-MODEVM is built around the 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 TLV320AIC3253EVM is one of the double-wide modular EVMs
that is designed to work with 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
