APPLICATIONS

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.
