Note: 1. Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to
the device. This is a 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.
Caution
Exposing the device to stress above those listed in Absolute Maximum Ratings could cause
permanent damage. The device is not meant to be operated under conditions outside the limits
described in the operational section of this specification. Exposure to Absolute Maximum Rating
conditions for extended periods may affect device reliability.
Recommended DC Operating Conditions (SSTL_18)
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.

Notes: 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
VDDQ of the transmitting device and VREF are 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. VDDQ tracks with VDD, VDDL tracks with VDD. AC parameters are measured with VDD, VDDQ and
VDDL tied together.
