1) 0 °C ≤ TA ≤ 70 °C
2) DDR400 conditions apply for all clock frequencies above 166 MHz
3) Under all conditions, VDDQ must be less than or equal to VDD.
4) Peak to peak AC noise on VREF may not exceed ± 2% VREF (DC). VREF is also expected to track noise variations in VDDQ.
5) VTT is not applied directly to the device. VTT is a system supply for signal termination resistors, is expected to be set equal to VREF, and
must track variations in the DC level of VREF.
6) VID is the magnitude of the difference between the input level on CK and the input level on CK.
7) The ration of the pull-up current to the pull-down current is specified for the same temperature and voltage, over the entire temperature
and voltage range, for device drain to source voltage from 0.25 to 1.0 V. For a given output, it represents the maximum difference between
pull-up and pull-down drivers due to process variation.
8) Inputs are not recognized as valid until VREF stabilizes.
9) Values are shown per component
