ABSTRACT:
A device for generating clock signals at different frequencies and in particular a fractional frequency of a reference frequency comprises a reference frequency generator which delivers at the output a reference signal having a frequency f, a frequency-divider for dividing by an integer p which delivers a signal at the frequency f/p at the output, and a digital inverter for extracting the harmonic frequency of order n and delivering a signal at a multiple frequency in order to obtain at the output of the device a signal of digital type having the frequency n/pf. A feedback loop impedance is coupled to the input and output of the inverter and preferably has a maximum value at the frequency nf. A load impedance is coupled to the input of the inverter and preferably has a minimum value at the frequency nf.
