There is no specific device VDD supply requirement for SSTL_18 compliance. However, under all conditions VDDQ must be less
than or equal to VDD.
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 0.5VDDQ of the transmitting device and VREF is expected to track variations is VDDQ.
Peak to peak AC noise on VREF may not exceed ±0.2% VREF(dc).
VTT of transmitting device must track VREF of receiving device.
VDDQ tracks with VDD, VDDL tracks with VDD.

The designer must meet the case temperature specifications for individual module components. Please refer to device spec.
Stresses greater than those listed may cause permanent damage to the device. This is a stress rating only and device
functional operation at or above the conditions indicated is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect reliability.
