1) VDDQ = 2.5 V ± 0.2 V, VDD = +2.5 V ± 0.2 V (DDR200 - DDR333); VDDQ = 2.6 V ± 0.1 V, VDD = +2.6 V ± 0.1 V (DDR400); 0 °C ≤ TA ≤ 70 °C
2) Input slew rate = 1 V/ns.
3) Inputs are not recognized as valid until VREF stabilizes.
4) VID is the magnitude of the difference between the input level on CK and the input level on CK.
5) The value of VIX is expected to equal 0.5 × VDDQ of the transmitting device and must track variations in the DC level of the same.
