Note: Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is stress
rating only, and functional operation of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
reliability.

operation at or above the conditions indicated is not implied. Exposure to absolute maximum rating conditions for extended periods
may affect reliability.
2. Up to 9850 ft.
3. The designer must meet the case temperature specifications for individual module components.

Note:
1. There is no specific device VDD supply voltage requirement for SSTL_18 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 (dc).
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 VDDDL tied together
