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 (tSK(O)) or within a single output bank (tSK(OB))
The time from the PLL controlled edge to the non controlled edge,
divided by the time between PLL controlled edges, expressed as a
percentage
