The PCM2903C is TIs 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, TIs 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.
