tSK(O)
The pin–to–pin skew is defined as the worst case difference in
propagation delay between any similar delay path within a
single device

T0
DC = tP/T0 x 100%
The time from the PLL controlled edge to the non controlled
edge, divided by the time between PLL controlled edges,
expressed as a percentage

TJIT(∅) = |T0–T1mean|
The deviation in t0 for a controlled edge with respect to a t0 mean in a
random sample of cycles

tJIT(CC) = |TN – TN + 1|
The variation in cycle time of a signal between adjacent cycles, over a
random sample of adjacent cycle pairs
