ODT DC Electrical Characteristics, assuming R
after proper ZQ calibration
The tolerance limits are specified after calibration with stable voltage and temperature. For the behavior of the tolerance
limits if temperature or voltage changes after calibration, see following section on voltage and temperature sensitivity.
The tolerance limits are specified under the condition that VDDQ = VDD and that VSSQ = VSS.
Pull-down and pull-up ODT resistors are recommended to be calibrated at 0.5 x VDDQ. Other calibration schemes may be
used to achieve the linearity spec shown above, e.g. calibration at 0.2 x VDDQ and 0.8 x VDDQ.
Not a specification requirement, but a design guide line.
