Output Driver DC Electrical Characteristics, assuming R
entire operating temperature range; after proper ZQ calibration
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 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.
4. Measurement definition for mismatch between pull-up and pull-down, MMPuPd:
Measure RONPu and RONPd, both at 0.5 x VDDQ:
7.4 Output Driver Temperature and Voltage sensitivity
If temperature and/or voltage change after calibration, the tolerance limits widen according to Table and Table .
DT = T - T (@calibration); DV= VDDQ - VDDQ (@calibration); VDD = VDDQ
dRONdT and dRONdV are not subject to production test but are verified by design and characterization.
