NOTE 1. 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.
NOTE 2. The tolerance limits are specified under the condition that VDDQ = VDD and that VSSQ = VSS.
NOTE 3. Pull-down and pull-up output driver impedances 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.
NOTE 4. Measurement definition for mismatch between pull-up and pull-down, MMPuPd:
Measure RONPu and RONPd, both at 0.5 * VDDQ:
RonPu – RonPd
MMPuPd
