Design of a PCIe card with USB and Ethernet

[HasHx]

Hello,

I am currently working on a USB 3.1, 10GigE to PCIe board, i was wondering if a FPGA would do the job? what can be the challenges with it?

Regards.

It can be done in an FPGA, but I've never done it. All FPGA vendors sell cores for it. I think EVERYTHING about implementing ethernet from scratch is challenging.

Can be done with a Xilinx 7 series FPGA.

Completely depends with how much knowledge you and or your team possess. As mentioned above, if using IP cores will reduce the efforts.

Hello,

I actually found a great core for Ethernet from Intel (X550) ((**broken link removed**)) which does exactly what i need it to do... for the USB i could not find any ICs for the USB 3.1 (Gen2) any suggestions? or should i do it with FPGA? if yes any sources that might help please?

Regards.

If your FPGA has PCIe hard IP you could implement USB using one of these

Peripheral


PCIe in FPGAs is common enough, you should be able to find some decent example designs. Not many FPGA's have built-in USB controllers.

Hello,
Have you tried products from Texas Instruments. They have many ICs with built-in USB/EThernet and PCIe.

FTDI has some options as well

If FPGA is not hard stop, there are many processors from TI,NXP/Freescale, Renesas etc which can support USB 3.1,PCIe and Ethernet. Even some high end controllers from Atmel or equalent will support these interfaces. Just search the manufacterers.
