10. Deterministic jitter is measured at 2.5Gbps with both K28.5 and 2
11. Cycle-to-cycle jitter definition: the variation of periods between adjacent cycles, T
12. Total jitter definition: with an ideal clock input of frequency <f
13. Crosstalk is measured at the output while applying two similar differential clock frequencies that are asynchronous with respect to each other

High frequency AC electricals are guaranteed by design and characterization.
Output-to-output skew is measured between outputs under identical input conditions.
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
respective inputs.
Random jitter is measured with a K28.7 character pattern, measured at <f
