Notes:
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.
Random jitter is measured with a K28.7 pattern, measured at
f
MAX
.
10. Deterministic jitter is measured at 2.5Gbps with both K28.5 and 2
23
–1 PRBS pattern.
11. 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.
12. 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.
