Notes:
1) VID(ac) specifices the allowable DC execution of each input of differential pair such as CK,
, DQS, , LDQS, , UDQS, and
.
2) VIX(ac) specifices the input differential voltage lVTR-VCPl required for switching, where VTR is the true input (such as CK, DQS, LDQS, or
UDQS) level and VCP is the complementary input (such
, , , or ) level. The minimum value is equal to VIH(DC) - VIL(DC).
3) The typical value of VOX(AC) is expected to be about 0.5VDDQ of the transmitting device and VOX(AC) is expected to track variations in VDDQ.
VOX(AC) indicates the voltage at which differential signals must cross.
