I_OH = 6 x I_REF and V_OH = 0.7V @ Z_O=50Ω (100Ω differential impedance).
2 _{Measured from differential waveform}
3 _{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).
6 _{The total variation of all Vcross measurements in any 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.
