The total variation of all Vcross measurements in any particular system. Note that this is a subset of V_cross_min/max (V_cross
absolute) allowed. The intent is to limit Vcross induced modulation by setting V_cross_delta to be smaller than V_cross absolute.

Slew rate is measured through the Vswing voltage range centered around differential 0V. This results in a +/-150mV window around
differential 0V.
4
Matching applies to rising edge rate of Clock / falling edge rate of Clock#. It is measured in a +/-75mV window centered on the average
cross point where Clock rising meets Clock# falling. The median cross point is used to calculate the voltage thresholds the oscilloscope
uses for the edge rate calculations.
5
Vcross is defined as voltage where Clock = Clock# measured on a component test board and only applies to the differential rising
edge (i.e. Clock rising and Clock# falling).
