LOW PHASE NOISE CLOCK MULTIPLIER
Description
The ICS601-21 is a low-cost, low phase noise, high
performance clock synthesizer for applications which
require low phase noise and low jitter. It is ICS’ lowest
phase noise multiplier. Using ICS’ patented analog and
digital Phase Locked Loop (PLL) techniques, the chip
accepts a 10 - 27 MHz crystal or clock input, and produces
output clocks up to 220 MHz at 3.3 V.
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 nor guaranteed.
