    The PCM2903EVM-U is an evaluation module for the PCM2903C USB audio codec. The EVM is supported by Windows® XP, Windows® Vista, Windows® 7, OSX and most operating systems which are compatible with USB class audio devices. The PCM2903EVM-U connects to a USB port of a PC. The USB interface provides power, control and streaming audio data to the EVM.

    The PCM2903C is single-chip, USB, stereo audio codec with a USB-compliant full-speed protocol controller and S/PDIF. The USB protocol controller requires no software code. The PCM2903C employs SpAct architecture, TI’s unique system that recovers the audio clock from USB packet data. On-chip analog PLLs with SpAct enable playback and record with low clock jitter, as well as independent playback and record sampling rates.

    Key Applications: USB Audio Speaker, USB Headset, USB Monitor, USB Audio Interface Box
