However under all conditions VDDQ must be less than or equal to VDD. 1.The value of VREF may be selected by the user to provide optimum noise margin in the system. Typically the value of VREF is expected to be about 0.5 x VDDQ of the transmitting device and VREF is expected to track variations in VDDQ. 2.Peak to peak AC noise on VREF may not exceed +/-2% VREF (DC). 3.VTT of transmitting device must track VREF of receiving device. 4.AC parameters are measured with VDD, VDDQ and VDDDL tied together.
