Slew rate is measured through the Vswing voltage range centered around differential 0V. This results in a +/-150mV window around
Matching applies to rising edge rate of Clock / falling edge rate of Clock#. It is measured in a +/-75mV window centered on the
Measured from differential waveform
Vcross is defined as voltage where Clock = Clock# measured on a component test board and only applies to the differential rising
The total variation of all Vcross measurements in any system. Note that this is a subset of V_cross_min/max (V_cross absolute)
