Table 5–95
Stratix II DQS delay buffer. Multiply the number of delay buffers that you
are using in the DQS logic block to get the maximum delay achievable in
your system. For example, if you implement a 90° phase shift at 200 MHz,
you use three delay buffers in mode 2. The maximum achievable delay
from the DQS block is then 3 × .416 ps = 1.248 ns.
