DATASHEET
LOCO™ PLL CLOCK MULTIPLIER
Description
The ICS502 LOCO
TM
is the most cost effective way to
generate a high-quality, high-frequency clock output and a
reference from a lower frequency crystal or clock input. The
name LOCO stands for Low Cost Oscillator, as it is
designed to replace crystal oscillators in most electronic
systems. Using Phase-Locked Loop (PLL) techniques, the
device uses a standard fundamental mode, inexpensive
crystal to produce output clocks up to 160 MHz.
Stored in the chip’s ROM is the ability to generate six
different multiplication factors, allowing one chip to output
many common frequencies (see table on page 2).
This product is intended for clock generation. It has low
output jitter (variation in the output period), but input to
output skew and jitter are not defined or guaranteed. For
applications which require defined input to output skew, use
the ICS570B.
