Notes: 1. The VDDQ of the device under test is referenced.
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.
5. 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, LDQS or UDQS) and VCP is the complementary input signal (such as
/CK, /DQS, /LDQS or /UDQS). 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.
