The DIR1701 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. The significant advantages of the DIR1701 are 96 kHz sampling rate capability and Low-jitter clock recovery by the Sampling Period Adaptive Controlled Tracking (SpAct) system. Input signal is reclocked with the patented Sampling period Adaptive controlled tracking system for maximum quality. These two features are required for recent consumer and professional audio instruments, in which the DIR has an interface to any kind of delta-sigma type ADC/DAC with 96 kHz sampling rate.
