FPGA 10gigabit Ethernet

(1/3) > >>

Thomas83:
Hello,
I am using OpenVPX board based on the Xilinx Zynq from model 5953 from PENTEK.
I need 10 gigabit ethernet communication.
My question is the following, can we use 10 gigabit ethernet instead of the PCIe Gen 3 x8 (8 differential pair Tx and 8 differential pair Rx) bus.
If we can, do we need an external ethernet PHY or not?

Thanks in advance,

Daixiwen:
You will need a PCB with an SFP+ socket connected to the GTY lines on the FPGA. The you can put any SFP+ module in there to have your 10 gigabit Ethernet connection.

Thomas83:
Hi Daixiwen,
Thank you for your reply.

If I understood,
I can use the PCIe (GTY) bus which comes out of the P2 connector (Cf. image attached in my previous message) to make 10GbE (fiber or RJ45 cooper)?

asmi:
Why don't you just insert a 10G network card into PCIE slot and call it a day?

It looks like it's P1 from what I'm seeing (or the VITA connector) but yes basically route a tx ad a rx pair to the SFP+ module. You will also need a small bunch of low frequency signals (i2c, rate select, status...)
The samtec connectors that you show are for board to board connection with your own protocol. It works too, but it's not 10GbE.
