100mV.
Output-to-output skew is measured between outputs under identical conditions.
Part-to-part skew is defined for two parts with identical power supply voltages at the same temperature and with no skew of the edges at the
respective inputs. Part-to-part skew includes variation in t
pd
.
10. Cycle-to-cycle jitter definition: The variation of periods between adjacent cycles, T
n
–T
n–1
where T is the time between rising edges of the output
signal.
11. Total jitter definition: With an ideal clock input of frequency
f
MAX
, no more than one output edge in 10

output edges will deviate by more than the
specified peak-to-peak jitter value.
12. Random jitter is measured with a K28.7 comma detect character pattern, measured at 1.25Gbps and 2.5Gbps.
