ICS601-21
ICS601-21 is LOW PHASE NOISE CLOCK MULTIPLIER manufactured by Renesas.
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 IDT’s lowest phase noise multiplier. Using IDT’s patented analog and digital Phase Locked Loop (PLL) techniques, the chip accepts a crystal or clock input, and produces output clocks up to 230 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.
Features
