Questions
How big is the RFclockgen PCB?
It measures 87.1 × 67.4 mm and has 4 copper layers, 1.6 mm thick.
What parts does the RFclockgen use?
75 parts, built around the ESP32-C6-WROOM-1-N8, CP2102N-A02-GQFN28, AP2112K-3.3 and ADF4351BCP. 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 RFclockgen KiCad files?
From the Jjbinstock/RF-Clock-Generator repository on GitHub, at the commit this page was made from: the board is RFclockgen.kicad_pcb and its schematic AUTODOWNLOAD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RFclockgen design in my own project?
Its repository states no licence, so its author keeps all rights: ask Jjbinstock before reusing the design.
