MK2745-21 Overview
The MK2745-21 is a low cost, low jitter, high performance clock synthesizer for DVD and other MPEG 2 based applications. Using analog PhaseLocked Loop (PLL) techniques, the device accepts a 27.00MHz fundamental mode crystal or clock input to produce multiple output clocks including the processor clock, the processor clock divided by two, 27 MHz, 24.576 MHz, and a selectable audio clock. The audio clocks are...
