DESCRIPTION

The PCM2900C/2902C are Texas Instruments' single-chip, USB, stereo audio codecs with a

USB-compliant full-speed protocol controller and

S/PDIF (PCM2902C only). The USB protocol

controller requires no software code. The

PCM2900C/2902C employ SpAct? architecture, TI's

unique system that recovers the audio clock from

USB packet data. On-chip analog PLLs with SpAct

architecture enable playback and record with low

clock jitter as well as independent playback and

record sampling rates.
