10. Random jitter is measured with a K28.7 character pattern, measured at <f
11. Deterministic jitter is measured at 2.5Gbps with both K28.5 and 2
12. Cycle-to-cycle jitter definition: the variation of periods between adjacent cycles, T
13. Total jitter definition: with an ideal clock input of frequency <f
14. Crosstalk-induced jitter is defined as the added jitter that results from signals applied to two adjacent channels. It is measured at the output

High-frequency AC-parameters are guaranteed by design and characterization.
Output-to-output skew is measured between two different outputs under identical input transitions.
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
