Figure 13. Propagation Delay (t
Figure 15. Output- -to- -Output Skew t
The time from the output controlled edge to the non--controlled
edge, divided by the time between output controlled edges,
expressed as a percentage
PCLK

Q
The pin--to--pin skew is defined as the worst case difference in
propagation delay between any similar delay path within a
single device
The variation in cycle time of a signal between adjacent cycles,
over a random sample of adjacent cycle pairs
