Notes to
(1) For possible reference input clock pins for each DLL, refer to
(2) You can configure each DQS/CQ and CQn pin with a phase shift based on one of two possible DLL output settings.

and CQn pins in the device where memory interfaces are supported on all sides of the
Stratix IV device.
DQS phase-shift circuitry is connected to the DQS logic blocks that control each
DQS/CQ or CQn pin. The DQS logic blocks allow the DQS delay settings to be
updated concurrently at every DQS/CQ or CQn pin.
