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
13. Crosstalk-induced jitter is defined as the added jitter that results from signals applied to the adjacent channel. It is measured at the output while

Input-to-Input skew is the difference in time between both inputs, measured at the same output, for the same temperature, voltage and
transition.
Output-to-Output skew is the difference in time between both outputs, receiving data from the same input, for the same temperature, voltage and
transition.
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.
Random jitter is measured with a K28.7 pattern, measured at ≤ f
where T is the time between rising edges of the output signal.
