The DIR1703 demultiplexes the channel status bit and user bit directly to serial output pins, and has dedicated output pins for the most important channel status bits. It also includes extensive errors reporting. The significant advantages of the DIR1703 are 96-kHz sampling rate capability and Low-jitter clock recovery by the Sampling Period Adaptive Controlled Tracking (SpAct) system. The input signal is reclocked with the patented Sampling period Adaptive controlled tracking system for maximum quality. These features are required for recent consumer and profes...
