Abstract
Device for generating a signal of parametrizable frequency comprising a phase locked loop including a generator of a reference signal, a phase-frequency comparator comprising a first input for receiving the reference signal, an oscillator controlled on the basis of the result output by the phase-frequency comparator, a fractional divider coupled between an output of the oscillator and a second input of the phase-frequency comparator, and a selector selectively linking an input of the oscillator either with an input of the generator, or with the output of the oscillator as a function of the multiplication ratio of the fractional divider.
