LOW PHASE NOISE CLOCK MULTIPLIER
Description
The ICS601-02 is a low cost, low phase noise, high
performance clock synthesizer for any application that
requires low phase noise and low jitter. The ICS601 is IDT’s
lowest phase noise multiplier. Using IDT’s 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 170 MHz at 3.3 V. A separate supply pin
is provided so that the output can be 2.5 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. For
applications which require defined input to output timing,
use the ICS670-01.

... Use decoupling capacitors of 0.1 µF in parallel with 0.01 µ important to have these capacitors as close as possible to the ICS601-02 supply pins. Disabling the REFOUT clock is also important for achieving low phase noise; lab tests have shown that this can reduce the phase noise by as much as 10 dBc/Hz ...
