Note:
1.
Inputs are not recognized as valid until VREF 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 VREF.
4.
VID is the magnitude of the difference between the input level on CK and the input level on .
