Slew rate dV/dt 2 Measured from differential waveform Slew rate is measured through the Vswing voltage range centered around differential 0V. This results in a +/-150mV window around differential 0V. 3 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 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. 7 8 9 Includes overshoot and undershoot. Measured from single-ended waveform Measured with scope averaging off, using statistics function. Variation is difference between min and max.
