Differential Signal Level Waveform
Differential AC Output Parameters
Symbol
Parameter
VOX(AC)
AC differential crosspoint voltage
Note: The typical value of VOX(AC) is expected to be about 0.5 x VDDQ of the transmitting device and VOX(AC) is expected to track variations in VDDQ. VOX(AC)
indicates the voltage at which differential output signals must cross.
