Preliminary Data Sheet
AMCC Proprietary
75
In the following examples, the data strobes (DQS) and the data are shown to be coincident. There is actually a
slight skew as specified by the SDRAM specifications, and there can be additional skew due to loading and signal
routing. It is recommended that the signal length for all of the eight DQS signals be matched.

Table 20. DDR SDRAM I/O Read Timing—T
SD
and T
HD
Notes:
1. T
SD
and T
HD
are measured under worst case conditions.
2. Clock speed for the values in the table is 333.33MHz.
3. The time values in the table include 1/4 of a cycle at 166MHz (3ns x 0.25 = 0.75 ns).
4. To obtain adjusted T
SD
and T
HD
values for lower clock frequencies, subtract 0.75 ns from the values in the table and add 1/4
of the cycle time for the lower clock frequency (e.g., T
SD
- 0.75 + 0.25T
CYC
).
