Calibrated Output Driver V-I Characteristics
DDR2 SDRAM output driver characteristics are defined for full strength calibrated operation as selected by the procedure
outlined in the Off-Chip Driver (OCD) Impedance Adjustment. The following tables show the data in tabular format suitable
for input into simulation tools. The nominal points represent a device at exactly 18 ohms. The nominal low and nominal high
values represent the range that can be achieved with a maximum 1.5 ohms step size with no calibration error at the exact
nominal conditions only (i.e. perfect calibration procedure, 1.5 ohm maximum step size guaranteed by specification). Real
system calibration error needs to be added to these values. It must be understood that these V-I curves are represented
here or in supplier IBIS models need to be adjusted to a wider range as a result of any system calibration error. Since this a
system specific phenomena, it cannot be quantified here. the values in the calibrated tables represent just the DRAM
portion of uncertainty while looking at one DQ only. If the calibration procedure is used, it is possible to cause the device to
operate outside the bounds of the default device characteristics tables and figure. in such a situation, the timing parameters
in the specification cannot be guaranteed. It is solely up to the system application to ensure that the device is calibrated
between the minimum and maximum default values at all times. If this cant be guaranteed by the system calibration
procedure, re-calibration policy and uncertainty with DQ to DQ variation, it is recommend that only the default values to be
used. The nominal maximum and minimum values represent the change in impedance from nominal low and high as a
result of voltage and temperature change from the nominal condition to the maximum and minimum conditions. If calibrated
at an extreme condition, the amount of variation could be as much as from the nominal minimum to the nominal maximum
or vice versa.
