DESCRIPTION

THD+N: 0.006% R_L> 10 kΩ, Self-

The PCM2704C/5C/6C/7C are TI's single-chip USB

stereo audio digital-to-analog converters (DACs) with

USB 2.0 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 areas (for example, vendor ID/product ID)

through the use of an external ROM (PCM2704C/6C)

or serial peripheral interface (SPI) (PCM2705C/7C).

The PCM2704C/5C/6C/7C also employ SpAct™

architecture, TI's unique system that recovers the

audio clock from USB packet data. On-chip analog

phase-locked loops (PLLs) with SpAct enable

playback with low clock jitter.
