The MK2704 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. The audio clock is frequency locked to the 27 MHz clock, assuring that the audio with zero ppm error and video will track perfectly. IDT manufactures the largest variety of Set-Top Box and multimedia clock synthesizers for all applications. Consult IDT to eliminate VCXOs, crystals and oscillators from your board.
