The ICS601-01 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, and also the lowest CMOS part in the industry. Using ICS' 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 at 3.3 V.
