Notes:
20. Measurement taken from differential waveform, from –0.35V to +0.35V.
21. Measurements taken from common mode waveforms, measure rise/fall time from 0.41 to 0.86V. Rise/fall time matching is defined as “the instantaneous difference
22. Measured in absolute voltage, i.e., single-ended measurement.
23. THIGH is measured at 2.4V for non-host outputs.
24. TLOW is measured at 0.4V for all outputs.
25. Probes are placed on the pins, and measurements are acquired between 0.4V and 2.4V for 3.3V signals (see test and measurement set-up section of this data
