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 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 170 MHz at 3.3 V. A separate supply pin is provided so that the output can be 2.5 V.
