Notes to
(1) The input reference clock for the DQS phase-shift circuitry can come from a PLL output clock or an input clock pin. For the exact PLL and input
(2) The dqsenable signal can also come from the Stratix III FPGA fabric.

Each DQS and CQn pin is connected to a separate DQS logic block, which consists of
the DQS delay chains, update enable circuitry, and DQS postamble circuitry, as shown
in
DQS Delay Chain
The DQS delay chains consist of a set of variable delay elements to allow the input
DQS/CQ and CQn signals to be shifted by the amount specified by the DQS
phase-shift circuitry or the logic array. There are four delay elements in the DQS delay
chain; the first delay chain closest to the DQS/CQ pin can either be shifted by the
DQS delay settings or by the sum of the DQS delay setting and the phase-offset
setting. The number of delay chains required is transparent because the
ALTMEMPHY megafunction automatically sets it when you choose the operating
frequency. The DQS delay settings can come from the DQS phase-shift circuitry on
either end of the I/O banks or from the logic array.
Delay elements in the DQS logic block have the same characteristics as the delay
elements in the DLL. When the DLL is not used to control the DQS delay chains, you
can input your own Gray-coded 6-bit or 5-bit settings using the
dqs_delayctrlin[5..0]signals available in the ALTMEMPHY megafunction.
These settings control 1, 2, 3, or all 4 delay elements in the DQS delay chains. The
ALTMEMPHY megafunction can also dynamically choose the number of DQS delay
chains required for the system. The amount of delay is equal to the sum of the delay
element’s intrinsic delay and the product of the number of delay steps and the value
of the delay steps.
