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.

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.
