5. Measured with 100mV input swing. See “Timing Diagrams” section for definition of parameters. High-frequency AC-parameters are guaranteed by
6. Random jitter is measured with a K28.7 comma detect character pattern, measured at 1.5Gbps.
7. Deterministic jitter is measured at f
8. Cycle-to-cycle jitter definition: the variation of periods between adjacent cycles, T
9. Total jitter definition: with an ideal clock input of frequency ≤ f
