1.9. UniPHY Interfaces
The following interfaces are on the UniPHY top-level file:
- Memory interface
- DLL sharing interface
- PLL sharing interface
- OCT interface
The UniPHY datapath uses the Altera PHY interface (AFI). The AFI is in a simple connection between the PHY and controller. The AFI is based on the DDR PHY interface (DFI) specification, with some calibration-related signals not used and some additional Intel® -specific sideband signals added.
For more information about the AFI, refer to AFI 4.0 Specification, in this chapter.
The Memory Interface
For information on the memory interface, refer to UniPHY Signals, in this chapter.
