Note 6.
The f
MAX value is specified as the minimum guaranteed maximum frequency (While maintaining TTL swing of 0.8V to 2.0V). Actual opera-
tional maximum frequency may be greater.
Note 7.
Part-to-Part Skew considering HIGH-to-HIGH transitions at common V
CC level.
Note 8.
V
PP(min) is the minimum input swing for which AC parameters are guaranteed.
Note 9.
Cycle-to-cycle jitter definition: The variation of periods between adjacent cycles, T
n – Tn–1,where T is the time between rising edges of the
output signal.
Note 10. Total jitter definition: with an ideal clock input of frequency
≤ f
MAX, no more than one output edge in 10
12 output edge will deviate by more than
the specified peak-to-peak jitter value.
