Notes: 1. VREF is expected to be equal to 0.5*VDDQ 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
2.VTT is not applied directly to the device. VTT is a system supply for signal termination resistors, is expected to be set equal to
V
REF, and must track variations in the DC level of VREF
3. VID is the magnitude of the difference between the input level on CK and the input level on CK.
