Notes:
10. Set-up and hold times apply to synchronous applications that intend to enable/disable before the next clock cycle. For asynchronous
11. Output-to-Output skew is measured between two different outputs under identical transitions.
12. Input-to-Input skew is the time difference between the two inputs to one output, under identical input transitions.
13. 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
14. Random Jitter is measured with a K28.7 character pattern, measured at <f
15. Cycle-to-Cycle Jitter definition: the variation of periods between adjacent cycles, T
16. Total Jitter definition: with an ideal clock input of frequency <f
17. Crosstalk is measured at the output while applying two similar differential clock frequencies that are asynchronous with respect to each

8. High-frequency AC-parameters are guaranteed by design and characterization.
9. Propagation delay is measured with input t
