ULTIPLIER
Description
The ICS501A LOCO
TM
is the most cost effective way to
generate a high quality, high frequency clock output
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.
Stored in the chip鈥檚 ROM is the ability to generate nine
different multiplication factors, allowing one chip to
output many common frequencies (see table on page
2).
The device also has an output enable pin which
tri-states the clock output when the OE pin is taken low.
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.
