This section describes the AC timing characteristics for the MSC8154.
2.6.1
DDR SDRAM AC Timing Specifications
This section describes the AC electrical characteristics for the DDR SDRAM interface.
2.6.1.1
DDR SDRAM Input AC Timing Specifications
Table 18 provides the input AC timing specifications for the DDR SDRAM when VDDDDR (typ) = 1.8 V.
Table 19 provides the input AC timing specifications for the DDR SDRAM when VDDDDR (typ) = 1.5 V.
Table 20 provides the input AC timing specifications for the DDR SDRAM interface.

Notes:
1.
tCISKEW represents the total amount of skew consumed by the controller between MDQS[n] and any corresponding bit that is
captured with MDQS[n]. Subtract this value from the total timing budget.
2.
At recommended operating conditions with VDDDDR (1.8 V or 1.5 V) ± 5%
3.
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.
