Description

The PCM2706 is TI's single-chip USB stereo audio DAC with USB 1.1 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 (PCM2706) SPI (PCM2705/7) or on request.  The PCM2706 employs SpAct(TM) 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.
