Note:

• Common mode voltage is a mean value of high and low states of one single-ended signal.

• Differential voltage swing is differential amplitude between signals of differential pair.

• Differential transitions should be only measured with good equipment (bandwith > 1GHz),

otherwise results will seem too slow.
