ICS512
Description
Features
The ICS512 is the most cost effective way to generate
a high-quality, high frequency clock output and a
reference clock 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 200 MHz. With a reference output, this chip plus an
inexpensive crystal can replace two oscillators
Stored in the chip’s ROM is the ability to generate nine
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.
