Notes: 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.
2. The tolerance limits are specified under the condition that VDDQ = VDD and that VSSQ = VSS.
3. Pull-down and pull-up output driver impedances are recommended to be calibrated at 0.5 × VDDQ. Other
calibration schemes may be used to achieve the linearity spec shown above, e.g. calibration at 0.2 ×
VDDQ and 0.8 × VDDQ.
4. Measurement definition for mismatch between pull-up and pull-down, MMPuPd:
Measure RONPu and RONPd, both at 0.5 × VDDQ:
RONPu -RONPd
MMPuPd =

Output Driver Temperature and Voltage Sensitivity
If temperature and/or voltage change after calibration, the tolerance limits widen according to the table Output Driver
Sensitivity Definition and Output Driver Voltage and Temperature Sensitivity.
∆T = T − T (@calibration); ∆V= VDDQ − VDDQ (@calibration); VDD = VDDQ
Note: dRONdT and dRONdV are not subject to production test but are verified by design and characterization.
