1. Inputs are not recognized as valid until V REF stabilizes.
2. VREF is expected to be equal to 0.5 V DDQ of the transmitting device, and to track variations in the DC level of the same. Peak-to-peak
noise on VREF may not exceed 2% of the DC value.
3. VTT is not applied directly to the DIMM. 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 V REF .
4. VID is the magnitude of the difference between the input level on CK and the input level on CK .
