PLL AUDIO CLOCK SYNTHESIZER DATASHEET MK2703 The MK2703 is a low-cost, low-jitter, high-performance PLL clock synthesizer designed to replace oscillators and PLL circuits in set-top box and multimedia systems. Using IDT’s patented analog Phase Locked Loop PLL techniques, the device uses a 27 MHz crystal or clock input to produce a buffered reference clock and a selectable audio clock.
