Product InformationDescriptionThe DEM-PCM2900B/2902B/2906B is an evaluation board for Texas Instruments' newly developed USB interface codecs, the PCM2900B, PCM2902B, and PCM2906B. The DEM-PCM2900B includes a PCM2900B device, a bus-powered USB codec without an S/PDIF interface. The DEM-PCM2902B includes a PCM2902B device, a bus-powered USB codec with an S/PDIF interface. The DEM-PCM2906B includes a PCM2906B 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 3.3V regulator, and a USB connector. The USB connector is mounted on the DEM-PCM2900B/2902B/2906B printed circuit board (PCB). Connecting a USB interface to this USB connector enables the evaluation of codec performance. The DEM-PCM2900B/2902B/2906B 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. Stereo audio output and input are available on two stereo mini-jacks. FeaturesThe PCM2900B/2902B/2906B support the following USB features:
