MK2745-21 Datasheet | Integrated Circuit Systems

MK2745-21 DVD/MPEG Clock Source Description 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 frequency locked to the 27.00MHz input using our patented zero ppm error techniques, allowing audio and video to track exactly, thereby eliminating the need for large buffer memory. MicroClock manufactures the largest variety of DVD, Set-Top...
