PCM2904DBG4 Datasheet PDF - TI

●The PCM2904DBG4 is a stereo USB1.1 CODEC with line-out bus-powered. The USB protocol controller works with no software code, but the USB descriptors can be modified in some areas. The PCM2904 employs SpAct™ architecture, its unique system that recovers the audio clock from USB packet data. On-chip analogue PLLs with SpAct enable playback and record with low clock jitter and with independent playback and record sampling rates.

● On-chip USB interface

● Partially programmable descriptors

● USB Adaptive mode for playback

● On-chip clock generator with single 12MHz clock source

● Single-ended voltage input

●This IC can be damaged by ESD. We recommend that all ICs be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
