Figure 39. Single-Ended Measurement Points for Rise and Fall Time Matching
The other detailed AC requirements of the SerDes reference clocks is defined by each interface protocol based on application
usage. Refer to the following sections for detailed information:
Rising edge rate (SD
n_REF_CLK) to falling edge rate
(SD
n_REF_CLK) matching

Notes:
1. Measurement taken from single ended waveform.
2. Measurement taken from differential waveform.
3. Measured from –200 to +200 mV on the differential waveform (derived from SD
n_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 38.
4. Matching applies to rising edge rate for SD
n_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 SD
n_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 SD
n_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 39.
