Note: (1) There is no specific device VDD supply voltage requirement for SSTL_1.8 compliance. However under all conditions VDDQ must be
less than or equal to VDD.
(2) 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.
(3) Peak to peak ac noise on VREF may not exceed +/- 2% VREF (ac).
(4) VTT of transmitting device must track VREF of receiving device.
(5) VDDQ tracks with VDD, VDDL tracks with VDD. AC parameters are measured with VDD, VDDQ and VDDL tied together.
