1. For best jitter performance, keep the input slew rate on pins 1,2,5,6 faster than 0.3 V/ns
2. Not in PLL bypass mode.
3. For best jitter performance, keep the input single ended slew rate on pins 3 or 4 faster than 1 V/ns
4. Only two unique frequencies above 350 MHz can be simultaneously output, Fvco/4 and Fvco/6.
5. Includes effect of internal series 22  resistor.
