Data Sheet
I/O Timing—DDR SDRAM T
DS
Notes:
1. All of the DQS signals are referenced to MemClkOut0(0).
2. The T
DS
values in the table include 3/4 of a cycle at the indicated clock speed.
3. To obtain adjusted values for lower clock frequencies, subtract 5.625 ns from the values in the table and add 3/4 of the cycle
time for the lower clock frequency (T
DS
- 5.625 + 0.75T
CYC
).

SA
, and T
HA
Notes:
1. T
SK
is referenced to MemClkOut0(0). T
SA
and T
HA
are referenced to MemClkOut0(90).
2. To obtain adjusted T
SA
values for lower clock frequencies, use 3/4 of the cycle time for the lower clock frequency and
subtract T
SK
maximum (0.75T
CYC
- T
SK
max).
3. To obtain adjusted T
HA
values for lower clock frequencies, use 1/4 of the cycle time for the lower clock frequency and add
T
SK
minimum (0.25T
CYC
+ T
SK
min).
