Channel-to-Channel Skew is defined as the difference between the propagation delay of one channel and that of the others on the same
chip with an event on the inputs.
Chip to Chip Skew is defined as the difference between the minimum and maximum specified differential propagation delays.

includes probe and jig capacitance.
For DS90C032E propagation delay measurements are from 0V on the input waveform to the 50% point on the output (ROUT).
