DESCRIPTION

The PCM2704/5/6/7 is TI's single-chip USB stereo

audio DAC with USB-compliant full-speed protocol

controller and S/PDIF. The USB-protocol controller

works with no software code, but USB descriptors

can be modified in some parts (for example, vendor ID/product ID) through the use of an external ROM

(PCM2704/6), SPI (PCM2705/7), or on request. (1)

The PCM2704/5/6/7 employs SpAct? architecture,

TI's unique system that recovers the audio clock from

USB packet data. On-chip analog PLLs with SpAct enable playback with low clock jitter.
