To generate a target frequency from a basic frequency, a phased signal of the basic frequency and of a phase controllable by a phase clock signal is generated in accordance with the invention, the target frequency being generated by dividing the frequency of the phased signal by an output dividing factor and the phase clock signal being generated from the phased signal irrespective of the target frequency. A wider range of target frequencies can be obtained in this way. Also, the switching pattern in which the phase of the phased signal is changed can be made independent of the state of the phased signal, thus giving further possible ways of acting on the target frequency.
