Notes:
10. Part-to-part skew is defined for two parts with identical power supply voltages at the same temperature and with no skew of the edges at the
11. Random jitter is measured with a K28.7 comma detect character pattern, measured at 2.5Gbps to 3.2Gbps.
12. Deterministic jitter is measured at 2.5Gbps to 3.2Gbps, with both K28.5 and 2
13. Cycle-to-cycle jitter definition: the variation of periods between adjacent cycles, T
14. Total jitter definition: with an ideal clock input of frequency ≤ f
15. Crosstalk is measured at the output while applying two similar clock frequencies that are asynchronous with respect to each other at the inputs.
