Questions
How big is the Serdes PCB?
It measures 71 × 30 mm and has 4 copper layers, 1 mm thick.
What parts does the Serdes use?
54 parts, built around the DS92LV16TVHG and SI5351C-B-GM. 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 Serdes KiCad files?
From the L0czek/serdes repository on GitHub, at the commit this page was made from: the board is serdes.kicad_pcb and its schematic serdes.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Serdes design in my own project?
Its repository states no licence, so its author keeps all rights: ask L0czek before reusing the design.
