The pin-to-pin skew is defined as the worst case differ-
ence in propagation delay between any similar delay
path within a single device.
Figure 13. Propagation Delay (t
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.
