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 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 MHz using our patented zero ppm error techniques. This allows audio and video to track exactly, thereby eliminating the need for large buffer memory. IDT manufactures a large variety of DVD, Set-top Box, and multimedia clock synthesizers for all applications. Consult IDT to eliminate crystals and oscillators from your board.
