Notes:
8. High-frequency AC-parameters are guaranteed by design and characterization.
9. Output-to-output skew is measured between outputs under identical conditions.
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
11. Random jitter is measured with a K28.7 character pattern, measured at 2.5Gbps.
12. DJ is measured at 2.5Gbps, 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
