includes a PCM2900C device, a bus-powered USB codec without an S/PDIF interface. The PCM2902C
includes a PCM2902C device, a bus-powered USB codec with an S/PDIF interface. The PCM2906C
includes a PCM2906C device, a bus-powered (500 mA) USB codec with an S/PDIF interface. Each
evaluation board also includes operational amplifiers for line input/output buffers, a 3.3-V regulator, and a
USB connector.

The USB connector is mounted on the PCM2900C/2902C/2906C printed circuit board (PCB). Connecting
a USB interface to this USB connector enables the evaluation of codec performance.
a USB interface to this USB connector enables the evaluation of codec performance.
The PCM2900C/2902C/2906C operates from the 5-V bus power supply of the USB. A 3.3-V IC regulator
is mounted on the board to provide power for analog circuitry and optionally for the codec.
