The VDDQ of the device under test is referenced.
VDDQ = 1.7V; VOUT = 1.42V.
VDDQ = 1.7V; VOUT = 0.28V.
The DC value of VREF applied to the receiving device is expected to be set to VTT.
After OCD calibration to 18Ω at TC = 25°C, VDD = VDDQ = 1.8V.

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.
