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:
Section 8.3.2, “AC Requirements for SGMII SD2_REF_CLK and SD2_REF_CLK”
Section 16.2, “AC Requirements for PCI Express SerDes Reference Clocks”
Section 17.2, “AC Requirements for Serial RapidIO SD1_REF_CLK and SD1_REF_CLK”

Notes:
1. Measurment taken from single ended waveform.
2. Measurment 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 52.
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 53.
