MK2745-21
REV D 042904
Description
The MK2745-21 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, 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 MHz using
our patented zero ppm error techniques. This allows audio
and video to track exactly, thereby eliminating the need for
large buffer memory.
ICS manufactures a large variety of DVD, Set-top Box, and
multimedia clock synthesizers for all applications. Consult
ICS to eliminate crystals and oscillators from your board.
Features

sampling rates
Selectable audio sampling frequencies support 32, 44.1,
and 48 kHz in most DACs
27 MHz fundamental crystal or clock input
Eight selectable processor frequencies
Fixed clocks of 27 and 24.576 MHz
Zero ppm in all clocks
25 mA output drive capability at TTL levels
Advanced, low-power, sub-micron CMOS process
Operating voltage of 3.0 V to 5.5 V
