MK2746
Description
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.
ICS manufacturers the largest variety of DVD, set top
box, and multimedia clock synthesizers for all
applications.
