PCM2903C - Stereo USB1.1 CODEC with line-out and S/PDIF I/O, Self-powered (HID Interface)

Updated : 2020-01-09 14:24:16
Description

The PCM2903C is TI’s single-chip, USB, stereo audio codec with a USB-compliant full-speed protocol controller and S/PDIF. The USB protocol controller requires no software code. The PCM2903C 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, as well as independent playback and record sampling rates.
