Pullup Characteristics for Full Strength Output Driver
Pulldown Characteristics for Full Strength Output Driver
DDR SDRAM Output Driver V-I Characteristics
DDR SDRAM Output driver characteristics are defined for full and half strength operation as selected by the EMRS bit A1.
Figures 3 and 4 show the driver characteristics graphically, and tables 8 and 9 show the same data in tabular format suitable for input
into simulation tools. The driver characteristcs evaluation conditions are:
Typical
25×C
Vdd/Vddq = 2.5V, typical process
Minimum
70×C
Vdd/Vddq = 2.3V, slow-slow process
Maximum
0×C
Vdd/Vddq = 2.7V, fast-fast process
Output Driver Characteristic Curves Notes:
1. The full variation in driver current from minimum to maximum process, temperature and voltage will lie within the outer bounding lines
the of the V-I curve of Figure 3 and 4.
2. It is recommended that the "typical" IBIS V-I curve lie within the inner bounding lines of the V-I curves of Figure 3 and 4.
3. The full variation in the ratio of the "typical" IBIS pullup to "typical" IBIS pulldown current should be unity
+/-
10%, for device drain to
source voltages from 0.1 to1.0. This specification is a design objective only. It is not guaranteed.
