Stereo USB1.1 CODEC with line-out (HID Interface) - PCM2900C
Datasheet
Stereo Audio Codec w/USB Interface, Single-Ended Analog In/Out & S/PDIF datasheet
 

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.
