This repository contains the schematics and firmware for a frequency divider used in an experiment for time resolved transmission electron microscopy. The frequency divider can operate up to 4 GHz and is optimized for low timing jitter. The jitter has not been determined by measurements, but calculations using the jiter of the individual components of the signal path lead to <5ps. The input is designed for 90-200mV pp.
The divider can be configured for a division factor of (2^a)(2^b) with a=0...3 and b=0...5.
CAUTION:
The NB6N239S chip is not manufactured anymore. It is highly recommended to re-design the board!

Questions
How big is the Frequenzteiler PCB?
It measures 96 × 61.9 mm and has 2 copper layers, 1 mm thick.
What parts does the Frequenzteiler use?
45 parts, built around the HMC988LP3E and MC100EPT21D. 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 Frequenzteiler KiCad files?
From the eduphys/frequency-divider repository on GitHub, at the commit this page was made from: the board is Elektronik/Frequenzteiler/Frequenzteiler.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Frequenzteiler design in my own project?
Its repository states no licence, so its author keeps all rights: ask eduphys before reusing the design.
