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
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

Patented zero ppm audio clock error for 256x and
384x 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
