DVD/MPEG Clock Source

The MK2746 is a low cost, low jitter, high performance clock synthesizer for DVD and other MPEG2 based applications. Using analog Phase Locked Loop (PLL) techniques, the device accepts a 27 MHz fundamental mode crystal or clock input to produce multiple output clocks including the processor clock, audio clock, bus driver clock, SDRAM clock and a Video clock. The audio clocks are frequency locked to the 27 MHz input using our patented zero ppm error techniques, allowing audio and video to track exactly, thereby eliminating the need for large buffer memory.
