4.5. Guidelines for Refclk #i is Active At and After Device Configuration

The Refclk #i is active at and after device configuration feature is only supported by Intel Agilex® 7 F-Tile devices mentioned in Appendix A.1 . In designs that target other OPN devices, you must set the Refclk #i is active at and after device configuration to On, and you must provide stable reference clocks for the system PLLs and FGT at and after device configuration time.
