MK2745-24 General Description


The MK2745-24 is a low cost, low jitter, high performance clock synthesizer for DVD and other MPEG 2 based applications. Using analog Phase- Locked Loop (PLL) techniques, the device accepts a 27.00 MHz fundamental mode crystal or clock input to produce multiple audio output clocks, a processor clock, and two 27 MHz clocks. The audio clocks are frequency locked to the 27.00 MHz 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 Box, and multimedia clock synthesizers for all applications. Consult MicroClock to eliminate crystals and oscillators from your board.
