The DUNE neutrino experiment far detector has a fiducial mass of 40kt. The O(1 M) readout channels are distributed over the 4 x 10kt modules and need to be synchronized to O(10ns) with a reliable, simple, affordable system. For the majority of channels a simple DC-balanced protocol is used, with clock and synchronization information encoded on the same fibre. The remaining channels use “White Rabbit” (IEEE-1588). Small scale tests show a timing jitter of <100ps. The DUNE timing system has been successfully prototyped at the ProtoDUNE-SP detector at CERN.
