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 (bandwidth > 1 GHz),
otherwise results will seem too slow.
