The DDR PHY-only solution ports are divided into the following groups:
- DFI interface—signals required when the DDR subsystem is configured for DDR-PHY mode. This interface allows a third-party DDR controller hosted in the fabric to connect directly to the PHY.
- SDRAM interface—signals connected to the DDR SDRAM.
The following illustration shows the DDR PHY-only solution ports.
