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, RDQS) and VCP is the complementary input signal (such as /CK, /DQS,
/RDQS). 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.
