6.4.3. DDR4 Routing Guidelines - Memory-Down (Discrete) Topologies

Agilex™ 5 E-Series Group B FPGAs support only discrete DDR4 components down on mother board, in both thin and thick PCB stackups. The maximum supported data rates depend on the selected topology and thickness of board. There are two topologies for memory-down configurations covered in this section:

  • DDR4 1 RANK x 8 interface.
  • DDR4 1 Rank x 16 interface.
