Patent ID: 7772928

Claim:
Arrangement for the phase synchronization of several devices, wherein one device is a master device and the other devices are slave devices, with a phase-synchronization unit for every device, each of which phase-synchronization unit comprises: a first controlled oscillator for generating a master-reference signal, a second controlled oscillator for generating a clock-pulse 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 itself is the master device, 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 originating from the phase-synchronization unit of the master device if the device itself is not the master device but a slave device, and a third phase detector, which, in order to control the second oscillator, compares the phase of a fourth comparison signal derived from the master-reference signal with the phase of a fifth comparison signal derived from the clock-pulse signal if the device itself is the master device.
