产品概述
The PCM2912A is the Texas Instruments single-chip, USB stereo audio codec with a USB,
2.0-compliant, full-speed protocol controller and an analog front-end (AFE) function for headset
applications.The USB protocol controller works with no software code, but USB descriptors can be
modified on request. The PCM2912A employs SpAct™ architecture,
TI’s unique system that recovers the audio clock from USB packet data. On-chip analog PLLs with
SpAct enables independent playback and record sampling rates with low clock jitters.
