PCM2906C - Stereo USB CODEC with line out and S/PDIF, Bus-powered

Updated : 2020-01-09 14:24:17
Description

The PCM2906C is Texas Instruments’ 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 PCM2906C 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.
