Overview

The PCM270xC are 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 and PCM2706C) or serial peripheral interface (SPI) (PCM2705C and PCM2707C). The PCM270xC also employ SpAct™architecture, a unique system that recovers the audio clock from USB packet data. Onchip analog phase-locked loops (PLLs) with SpAct enable playback with low clock jitter.
