DESCRIPTION
The PCM2900/2902 is Texas Instruments single-chip
USB stereo audio codec with USB-compliant full-speed
protocol controller and S/PDIF (only PCM2902). The
USB protocol controller works with no software code,
but the USB descriptors can be modified in some areas
(e.g., vendor ID/product ID). The PCM2900/2902
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 and with independent playback and record
sampling rates.
