Termination IV Characteristic at 60 Ohms
Figure 55
represents the DQ termination Pull-Up IV characteristic under process, voltage and temperature best
and worst case conditions. The actual DQ termination Pull-Up current must lie between these two bounding
curves. The value of the external ZQ resistor is 240
,
setting the nominal DQ termination impedance to 60
.
(Extended Mode Register programmed to ZQ/4).

60 Ohm Active Termination Characteristic
Table 38
lists the numerical values of the minimum and maximum allowed values of the output driver termination
IV characteristic.
