README
README.mdThe goal of this project is to make a device that can pipe displayport and USB 3 signals over a single 25 gbps fiber and provide kvm switch to switch between different sources.
Hardware
For this project the Xilinx FPGA XCKU5P-2FFVB676I has been chosen. It has 16 transceivers capable of 25 gbps and is reasonably priced at around 80 euros. The hardware is broken up into various pieces, this is to reduce production costs by being able to reuse parts and reduce costs for prototyping if mistakes are made.
The hardware can be broken up into the following pieces:
- FPGA board : The board that houses the FPGA and all the hardware to power/turn on the FPGA.
- Base board : The board that provides the fiber connections and main power supply. It also has an ESP32-P4 which interfaces with the FPGA for control.
- IO board : A board that provides either Displayport/usb inputs or outputs.
- USB front hub: A compact usb hub used for front IO.
Status
Currently 3 working FPGA cards have been produced. And the fiber optic ports on the base board have been validated being capable of sending/receiving 25 gbps signals.

Questions
How big is the Base board PCB?
It measures 119.8 × 129.8 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Base board use?
236 parts, built around the TPS53318DQPR, TLV62569DBV, TPS56637RPAR and W25Q128JVSIQ. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Base board KiCad files?
From the jorisplusplus/pcdock repository on GitHub, at the commit this page was made from: the board is base_board/base_board.kicad_pcb and its schematic base_board/USB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Base board design in my own project?
Its repository states no licence, so its author keeps all rights: ask jorisplusplus before reusing the design.
