Stereo USB1.1 DAC With Line-out And S/PDIF Output, Bus/Self-powered (I2S Interface)

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.
