Differential input AC Logic Level
Notes:
1. VID(AC) specifies the input differential voltage |VTR -VCP | required for switching, where VTR is the true input signal (such as CK, DQS and
2. The typical value of VIX(AC) is expected to be about 0.5 x VDDQ of the transmitting device and VIX(AC) is expected to track variations in
3. Refer to Overshoot/undershoot specifications for Vpeak value: maximum peak amplitude allowed for overshoot and undershoot.

VOX (ac) ac differential crosspoint voltage
VCP is the complementary input signal (such as CK or DQS). The minimum value is equal to VIH(AC) - VIL(AC).
VDDQ. VIX(AC) indicates the voltage at which differential input signals must cross.
VDDQ. VOX(AC) indicates the voltage at which differential output signals must cross.
