立体声音频DAC，带有USB接口，单端耳机输出和S / PDIF输出 Stereo Audio DAC with USB Interface, Single-Ended Headphone Output and S/PDIF Output
The PCM270xC are 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 and PCM2706C or serial peripheral interface SPI PCM2705C and PCM2707C. The PCM270xC 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.
