DESCRIPTION
The PCM2900/2902 is Texas Instruments' single-chip
USB stereo audio codec with USB-compliant
full-speed protocol controller and S/PDIF (only
PCM2902). The USB protocol controller works with
no software code, but the USB descriptors can be
modified in some areas (e.g., vendor ID/product ID).
The PCM2900/2902 employs 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 and with independent playback and record
sampling rates.

The descriptor can be modified by changing a mask.
