Introduction
The TLV320AIC3109EVM-K is a complete evaluation and demonstration kit, which includes the
TLV320AIC3109EVM and a USB-based motherboard called the USB-MODEVM Interface board. The
TLV320AIC3109EVM-K is operational with one USB cable connection to a personal computer. The USB
connection provides power, control, and streaming audio data to the EVM kit for reduced setup and
configuration. The EVM kit also provides connection points for control signals, audio data, and power for
advanced operation, which allows prototyping and connection to the end-user system evaluation. The
TLV320AIC3109EVM-K is controlled and configured with the TLV320AIC310xEVM-K Graphical User
Interface (GUI) Software, compatible with Microsoft
®
Windows
®
operating systems.

TLV320AIC3109EVM-K Block Diagram
The TLV320AIC3109EVM consists of two separate circuit boards, the USB-MODEVM and the
TLV320AIC3109EVM. The USB-MODEVM is built around a TAS1020B streaming audio USB controller
with an 8051-based core.
The USB-MODEVM has two EVM positions that allow for the connection of two small evaluation modules
or one larger evaluation module. The TLV320AIC3109EVM is designed to fit over both of the smaller
evaluation module slots as shown in
