DESCRIPTION

= 3.3 V

The PCM2901/2903 is TI’s single-chip USB stereo

audio codec with USB-compliant full-speed protocol

controller and S/PDIF (only PCM2903). The USB

protocol controller works with no software code, but the

USB descriptors can be modified in some areas (for

example, vendor ID/product ID). The PCM2901/2903

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.
