Absolute Maximum Ratings
Note: Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is stress
Environmental Parameters
Note:
1. Stresses greater than those listed may cause permanent damage to the device. This is a stress rating only, and device functional

3. The designer must meet the case temperature specifications for individual module components.
DC Electrical Characteristics and Operating Conditions
(T
Note:
1. There is no specific device VDD supply voltage requirement for SSTL_18 compliance. However under all conditions VDDQ must be
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
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
