7.4.3. DQS Phase-Shift Circuitry

The Arria® V DLL provides phase shift to the DQS/CQ/CQn/QK# pins on read transactions if the DQS/CQ/CQn/QK# pins are acting as input clocks or strobes to the FPGA.

The following figures show how the DLLs are connected to the DQS/CQ/CQn/QK# pins in the various Arria® V variants.
