    Notes:
    1. Use an external 100
    resistor to provide load termination for a differential clock. See Figure 3.
    2. For best jitter performance, keep the midpoint differential input slew rate on pins 1,2,5,6 faster than 0.3 V/ns.
    3. Minimum input frequency in clock buffer mode (PLL bypass) is 5 MHz. Operation to 1 MHz is also supported in buffer
    mode, but loss-of-signal (LOS) status is not functional.
    4. For best jitter performance, keep the mid point input single ended slew rate on pins 3 or 4 faster than 1 V/ns.
    5. Not in PLL bypass mode.
    6. Only two unique frequencies above 350 MHz can be simultaneously output, Fvco/4 and Fvco/6. See "3.3. Synthesis
    Stages" on page 18.
    7. CML output format requires ac-coupling of the differential outputs to a differential 100
    load at the receiver.
    8. Includes effect of internal series 22
    resistor.
