DDR and DDR2 SDRAM
Table 18 provides the input AC timing specifications for the DDR SDRAM when GVDD(typ) = 2.5 V.
Table 19 provides the input AC timing specifications for the DDR SDRAM interface.
Figure 4 illustrates the DDR input timing diagram showing the tDISKEW timing parameter.

Notes:
1. tCISKEW represents the total amount of skew consumed by the controller between MDQS[n] and any corresponding bit that
will be captured with MDQS[n]. This should be subtracted from the total timing budget.
2. The amount of skew that can be tolerated from MDQS to a corresponding MDQ signal is called tDISKEW. This can be
determined by the equation: tDISKEW = ± (T/4 – abs (tCISKEW)); where T is the clock period and abs (tCISKEW) is the absolute
value of tCISKEW.
3. This specification applies only to the DDR interface.
