Slew Rate
Statistical measurement on single-ended signal
using oscilloscope math function. (Scope

mV
Measurement on single ended signal using
absolute value. (Scope averaging off)

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.
