Notes:
1. Measurement taken from single ended waveform.
2. Measurement taken from differential waveform.
3. Measured from –200 mV to +200 mV on the differential waveform (derived from SDn_REF_CLK minus SDn_REF_CLK).
The signal must be monotonic through the measurement region for rise and fall time. The 400 mV measurement window is
centered on the differential zero crossing. See Figure 63.
4. Matching applies to rising edge rate for SDn_REF_CLK and falling edge rate for SDn_REF_CLK. It is measured using a
200 mV window centered on the median cross point where SDn_REF_CLK rising meets SDn_REF_CLK falling. The median
cross point is used to calculate the voltage thresholds the oscilloscope is to use for the edge rate calculations. The Rise
Edge Rate of SDn_REF_CLK should be compared to the Fall Edge Rate of SDn_REF_CLK, the maximum allowed
difference should not exceed 20% of the slowest edge rate. See Figure 64.
