11. Part-to-part skew is defined for two parts with identical power supply voltages at the same temperature, same transition edge, and no skew at
the edges at the respective inputs.
12. Random jitter is measured with a K28.7 pattern, measured at
f
MAX
.
13. Deterministic jitter is measured at 2.5Gbps with both K28.5 and 2

–1 PRBS pattern.
14. Cycle-to-cycle jitter definition: the variation period between adjacent cycles over a random sample of adjacent cycle pairs. t

where T is the time between rising edges of the output signal.
15. Total jitter definition: with an ideal clock input frequency of
f
MAX
(device), no more than one output edge in 10^12 output edges will deviate by
more than the specified peak-to-peak jitter value.
High-frequency AC-parameters are guaranteed by design and characterization.
Input-to-Input skew is the time difference between the two inputs and one output, under identical input transitions.
Input-to-Input Skew is included in IN-to-Q propagation delay.
