Figure 6. Output–to–output Skew tSK(O)
The pin-to-pin skew is defined as the worst case difference in
propagation delay between any two similar delay path within a
single device
The time from the PLL controlled edge to the non controlled
edge, divided by the time between PLL controlled edges,
expressed as a percentage
