Notes:
1. Frequency at which guaranteed for functionality. V
OH and VOL levels are guaranteed at DC only.
2. The f
MAX value is specified as the minimum guaranteed maximum frequency. Actual operational maximum frequency may be greater.
3. Device-to-Device Skew considering HIGH-to-HIGH transitions at common V
CC level.
4. Within-Device Skew considering HIGH-to -HIGH transitions at common V
CC level.
5. Within-Device Skew considering LOW-to-LOW transitions at common V
CC level.
6. 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.
7. Total jitter definition: with an ideal clock input of frequency ≤ fMAX, no more than one output edge in 10
12 output edge will deviate by more than the
specified peak-to-peak jitter value.
