Device for generating a clock signal by frequency multiplication

A device for generating a pulse signal, comprising:

• an input configured to receive an initial pulse signal having an initial period;
• an oscillator configured to generate at least one oscillator signal;
• a first stage synchronized with the at least one oscillator signal and configured to deliver:
• a secondary pulse signal having a separation between two successive pulses that is representative of an integer part of a division of the initial period by an integer N;
• and
• an auxiliary signal representative of a fractional part of the division and containing, for each pulse of the secondary pulse signal, an indication of a time shift to be applied to the pulse taking into account the separation between the pulse and a preceding pulse;
• and
• a second stage that receives the successive pulses of the secondary signal and the corresponding shift indications and is configured to generate the successive corresponding pulses of the pulse signal.
