How can I support legacy SFP modules with Agilex™ 7 FPGA F-Tile receivers? - How can I support legacy SFP modules with Agilex™ 7 FPGA F-Tile receivers?
Description Altera® Agilex™ 7 FPGA device F-Tile receivers cannot tolerate 2V pk-pk signals from legacy SFP modules. Resolution You can support legacy SFP modules by adding inline 6dB RF attenuators in between the SFP module and the Agilex™ 7 device F-Tile receiver. You must also power sequence the SFP module, ensuring that it powers up after the FPGA is configured. The Agilex™ 7 device F-Tile equalizer in Auto Adaptation mode should open the RX eye for reduced amplitude SFP+ signals.
