Data Sheet
Figure 10 shows the data strobe (DQS) and the data 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.
Figure 10. DDR SDRAM Memory Data and DQS
Table 20. DDR SDRAM I/O Read Timing—TSD and THD
Notes:
1. TSD and THD 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 TSD and THD 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., TSD - 0.75 + 0.25TCYC).
