FPGA carrier board PCB Review
Budget: $30 – $250 USD
I have an FPGA carrier board and I am interested in someone to review it and make any suggestions for improvement. This is a carrier board for an Alinx FPGA core board. It is basically a version of Alinx's carrier board with all the parts I don't need removed. The board has 10G Ethernet via an SFP, Gigabit copper Ethernet, USB 2.0, and a few minor things. I developed this board because I need to generate the SFP clock differently, and the off-the-shelf board cannot accommodate the change.
I stuck closely to Alinx's design for maximum compatibility with our current usage of the Alinx board, so this request concerns not the parts but the PCB layout. It is a 4-layer design in KiCad. I tried to take care with impedance and layout, but a more experience set of eyes might see where it could be better, so I am particularly interested in comments on or approval of the higher-speed areas, the SFP and 1G Ethernet.
I have attached a rendering to give a sense of the board and highlighting the areas of particular interest.
