Abstract

The invention concerns a device for providing a spread frequency clock signal, comprising: —an input (51) to receive a first clock signal having a first frequency; —a programmable clock divider (52) to generate the spread frequency clock signal from the first clock signal; —a first Feedback Shift Register (21), FSR, comprising at least one stage, the FSR being adapted to generate any of an odd number M of different values, the FSR being adapted to pseudo-randomly generate a first sequence of first output values, each corresponding to one of said M different values, and to provide a first output value, according to the sequence, during each clock cycle of the spread frequency clock signal; —a control unit (22) adapted to select a division factor of the programmable clock divider based on the first output value of the FSR during each clock cycle of the spread frequency clock signal; —an output (53) for providing the spread frequency clock signal.
