The 601-02 is a low cost, low phase noise, high performance clock synthesizer for any application that requires low phase noise and low jitter. The 601 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 670-01.
