Notes:

7.

High-frequency AC parameters are guaranteed by design and characterization.

8.

Within device skew is measured between two different outputs under identical input transitions.

9.

Part-to-part skew is defined for two parts with identical power supply voltages at the same temperature and no skew at the edges at the respective

inputs.

10. Set-up and hold times apply to synchronous applications that intend to enable/disable before the next clock cycle. For asynchronous applications,

set-up and hold times do not apply.

11. Random jitter is measured with a K28.7 pattern, measured at

≤f

13. Cycle-to-cycle jitter definition: The variation period between adjacent cycles over a random sample of adjacent cycle pairs.

t

14. Total jitter definition: with an ideal clock input frequency of

≤ f

than the specified peak-to-peak jitter value.
