Cross-Over Voltage for High-Speed Signals
The Cross-Over is defined as that point where the Differential line voltage becomes zero. The voltage
value at this point is called the Cross-Over Voltage and the time v alue is called the Cross-Over Time.
The following algorithms are used for High Speed signals for Cross-Over voltage.
for High Speed y=0

Where:
p1 and p2 are the consecutive data points of a single-ended signal.
