PCLK
PCLK
The time from the output controlled edge to the non–controlled
edge, divided by the time between output controlled edges,
expressed as a percentage
Q X
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
