Introduction
The PCM3070EVM is in the Texas Instruments (TI) modular EVM form factor, which allows direct
evaluation of the device performance and operating characteristics and eases software development and
system prototyping.

The PCM3070EVM-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.

PCM3070EVM-K Block Diagram
The PCM3070EVM-K consists of two separate circuit boards, the USB-MODEVM and the PCM3070EVM.
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 PCM3070EVM is one of the double-wide modular EVMs that is designed to work
with the USB-MODEVM.

The simple diagram of
shows how the PCM3070EVM 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

The USB-MODEVM has two EVM positions that allow for the connection of two small evaluation modules
or one larger evaluation module. The PCM3070EVM is designed to fit over both of the smaller evaluation
module slots as shown in
