Guaranteed by design and characterization, not 100% tested in production.
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 for Clock and falling edge rate for Clock#. It is measured using a +/-75mV window centered on the
Guaranteed by design and characterization, not 100% tested in production.

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 edge (i.e.
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)
