1_{Guaranteed by design and characterization, not 100% tested in production.}
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 for Clock and falling edge rate for Clock#. It is measured using 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 is to use 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 particular system. Note that this is a subset of Vcross_min/max (Vcross}
absolute) allowed. The intent is to limit Vcross induced modulation by setting Δ-Vcross to be smaller than Vcross absolute.
7 _{At default SMBus settings.}
