1. For best jitter performance, keep the midpoint differential 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 mid point 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. See "3.3. Synthesis
5. Includes effect of internal series 22  resistor.
6. Use an external 100  resistor to provide load termination for a differential clock. See Figure 3.
