10. Output-to-output skew is measured between two different outputs under identical conditions.
11. 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
12. Random jitter is measured with a K28.7 character pattern, measured at <f
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 differential clock frequencies that are asynchronous with respect to each
