Description

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 requestThe descriptor can be modified by changing a mask; contact your local representative for details.. 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.
