Since 2022, CERN uses White Rabbit to distribute the radio frequency signal in the SPS accelerator and the LHC accelerator is planned to also use White Rabbit for the next run (2030).

This talk will give a short overview of the CERN accelerator complex, how RF is used to accelerate protons and what is White Rabbit. It will then discuss why the RF phase is very important for an accelerator, how clocks are synchronized, how RF is computed, digitally distributed and locally regenerated using dedicated electronics.
