An apparatus for the phase synchronization of several devices, wherein one device is the master device and the other devices are slave devices, with a phase synchronization unit for every device, each of which has: a first controlled oscillator for producing a master reference signal, a first phase detector which, in order to control the first oscillator, compares the phase of a first comparison signal derived from the master reference signal with the phase of a second comparison signal derived from an auxiliary reference signal if the device is itself the master device and a second phase detector which, in order to control the first oscillator, compares the phase of a third comparison signal derived from the master reference signal with the phase of a reference signal coming from the phase synchronization unit of the master device if the device is not itself the master device but a slave device.
