8. Measured with 50Ω to V CC /2 termination.
9. f max limited by skew spec. Outputs will generate valid CMOS signals up to 180MHz.
10. See Applications Info section for more jitter information.
11. Input reference frequency is bounded by VCO lock range and feedback divide selection.
12. t pd is specified for 50MHz input reference, the window will shrink/grow proportionally from the minimum limit with shorter/linger reference
periods. The t pd does not include jitter.
