DESCRIPTION
The PCM2904/2906 is Texas Instruments single-chip
USB stereo audio codec with USB-compliant full-speed
protocol controller and S/PDIF (PCM2906 only). The
USB protocol controller works with no software code,
but the USB descriptors can be modified in some areas
(for
example,
vendor
PCM2904/2906
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 and with
independent playback and record sampling rates.
