Notes: 1. The VDDQ of the device under test is reference.
2.VDDQ = 1.7V; VOUT = 1.42V.
3.VDDQ = 1.7V; VOUT = 0.28V.
4.The DC value of VREF applied to the receiving device is expected to be set to VTT.

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 x 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 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.
