The first Detection Units of the KM3NeT infrastructure, whose main goal is the
detection of cosmic neutrinos, are currently being deployed on the Mediterranean sea bed. The
collaboration has chosen White Rabbit technology for providing sub-nanosecond synchronization
between the Digital Optical Modules, the functional detection units of the detector. White Rabbit
functionality is provided by the main front-end electronics board, the so-called Central Logic
Board, that embeds both, the White Rabbit firmware, as an IP core on a XILINX Kintex 7 FPGA,
and the tunable oscillators, the hardware needed by the White Rabbit technology. The Central
Logic Board also digitizes the data provided by 31 photomultiplier, which detect the Cherenkov
radiation produced by neutrinos, it controls the acoustic signals and the rest of the instrumentation
and it provides all the communications interfaces. The present paper describes the Central Logic
Board of KM3NeT and the network topology focusing on how it provides synchronization
