Datasheet
LOW PHASE NOISE 1 TO 5 CLOCK MULTIPLIER
Description
The ICS601-25 is a low-cost, low phase noise, high
performance clock synthesizer for applications which
require low phase noise, low jitter, and low skew fanout. It is
IDT’s lowest phase noise multiplier, and also the lowest
CMOS part in the industry. Using IDT’s patented analong
and digital Phase Locked Loop (PLL) techniques, the chip
accepts a 10-27 MHz crystal or clock input, and produces
output clocks up to 156 MHz.
