MAX 10 Ethernet SFP Solution

Greetings. I would like to use the MAX 10 FPGA in an design which requires Ethernet connectivity. Can I implement a Cu SFP to connect the Ethernet to the FPGA? I have reviewed the Triple Speed Et...

    Thanks Rex for the explanation.


    Just to top up further on Rex input here.


    Yes, different FPGA product family may have slightly variance of different TSE IP support feature.


    I looked at the TSE IP in Max10 and it only support Ethernet MAC and none of the physical layer.

    • Max 10 TSE MAC IP only expose GMII or RGMII interface to be connected to external PHY chip
    • Whether the external PHY chip can be connected to SFP port or not will depends on the external PHY chip capability


    Thanks.

    Thanks for the explanation dlim - I will use a GMII/RGMII external PHY chip and RJ-45/magnetics to connect to the Ethernet since a direct connection from an SFP to the MAX 10 FPGA is not supported.
