DDR and DDR2 SDRAM AC Electrical Characteristics

This table provides the input AC timing specifications for the DDR SDRAM interface when GVDD(typ) = 2.5 V.

This figure shows the input timing diagram for the DDR controller.

Notes:

1. AC timing values are based on the DDR data rate, which is twice the DDR memory bus frequency.

2. Maximum possible skew between a data strobe (MDQS[n]) and any corresponding bit of data (MDQ[8n + {0...7}] if 0

≤n ≤7)

or ECC (MECC[{0...7}] if n = 8).
