12. Measured from differential waveform.

13. Slew rate is measured through the Vswing voltage range centered around differential 0 V. This results in a

±150 mV window around

differential 0 V.

14. Matching applies to rising and falling edge rate of differential waveform. It is measured using a

±75 mV window centered on the average cross

point where the clock rising meets clock# falling. The median cross point is used to calculate voltage thresholds that the oscilloscope uses

to calculate the slew rate. Measurement taken using a 100

W differential impedance 5” trace PCB.

15. 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).

16. 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.

17. Measured from single−ended waveform

18. Measured with scope averaging off, using statistics function. Variation is difference between min and max.
