10. Random Jitter is measured with a K28.7 pattern, measured at <f
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

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