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 VCP is the complementary input signal (such as /CK, /DQS). The
minimum value is equal to VIH(AC) − VIL(AC).
2. The typical value of VIX(AC) is expected to be about 0.5 × VDDQ of the transmitting device and VIX(AC)
is expected to track variations in VDDQ . VIX(AC) indicates the voltage at which differential input signals
must cross.
3. The typical value of VOX(AC) is expected to be about 0.5 × 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.
