differential output signal. See Figure 1.

7.

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

8.

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.

9.

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

≤f

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

T

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

≤ f

than the specified peak-to-peak jitter value.

14. 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.

15. See “Timing Diagrams,” Figure 1a.
