Although DM is an input -only pin, the input capacitance of this pin must model the input capacitance of the DQ and DQS pins. This is required to match signal propagation times of DQ, DQS, and DM in the system. 3. Unused pins are tied to ground. 4. This parameteer is sampled. For DDR266 and DDR333 VDDQ = +2.5V +0.2V, VDD = +3.3V +0.3V or +0.25V+0.2V. For DDR400, VDDQ = +2.6V +0.1V, VDD = +2.6V +0.1V. For all devices, f=100MHz, tA=25°C, Vout(dc) = VDDQ/2, Vout(peak to peak) = 0.2V. DM inputs are grouped with I/O pins - reflecting the fact that they are matched in loading (to facilitate trace matching at the board level). Rev. 1.1 January 2007 11 Page
