An integrated circuit includes first and second oscillators. A controllable switch has a signal input connected to a signal output of the second oscillator. A modulator has two signal inputs each being coupled to a signal output of a respective one of the first oscillator and the controllable switch. At least one controllable reversing switch has two signal inputs each being connected to a signal output of a respective one of the modulator and the controllable switch. A controllable frequency divider has a signal input connected to a signal output of the second oscillator. Two signal input terminals are each connected to a modulation input of a respective one of the oscillators, and two input terminals are each connected to the frequency control input of a respective one of the oscillators. Signal output terminals are each connected to the signal output of a respective one of the first oscillator, the at least one controllable reversing switch, the frequency divider, and the second oscillator. Control terminals are respectively connected to the control input of the frequency divider, to the control input of the controllable switch and the switch input of the first oscillator, and to the control input of the at least one controllable reversing switch.
