Abstract
A device and method is described for the frequency division of an input clock signal, in which from the input clock signal at least two output clock signals are generated, with an output pulse frequency equal to an input pulse frequency divided by a given factor, whereby with a phase detector a phase difference is measured between the at least two output signals and each of the at least two output clock signals is either inverted or not inverted, as a function of the phase difference determined. A method of this type is particularly suitable for the demultiplexing of an input data signal, and can also be designed to be multi-step.
