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.

Device and method for generating a signal of parametrizable frequency

A device processes a received radio signal. Circuitry formulates voltage samples of the radio signal. Analog processing of those samples is performed. Then, digital processing is performed on the output of the analog processing. The circuitry for formulating voltage samples is configured to ensure a processing of the samples prior to the digital processing.
