DDR SDRAM AC Electrical Characteristics
This section provides the AC electrical characteristics for the DDR SDRAM interface.
6.2.1
DDR SDRAM Input AC Timing Specifications
Table 18 provides the input AC timing specifications for the DDR2 SDRAM when Dn_GVDD(typ)=1.8 V.
Table 19 provides the input AC timing specifications for the DDR SDRAM when Dn_GVDD(typ)=2.5 V.
Table 20 provides the input AC timing specifications for the DDR SDRAM interface.

Note:
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 following equation: tDISKEW =+/–(T/4 – abs(tCISKEW)) where T is the clock period and
abs(tCISKEW) is the absolute value of tCISKEW.
3. Maximum DDR1 frequency is 400 MHz.
