PCM2903C - Texas Instruments

PCM2903C Stereo Audio Codec

The PCM2903C is TI's 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. Onchip analog PLLs with SpAct enable playback and record with low cloc.
