Abstract
An integrated circuit includes a closed loop oscillator circuit portion. The closed loop oscillator circuit portion has an input for a reference clock signal and an output providing an output clock signal to one or more further components of the integrated circuit. The output clock signal has an average output frequency derived from the reference clock signal. The closed loop oscillator circuit portion is operable in a spread spectrum mode in which the closed loop oscillator circuit portion varies a frequency of said output clock signal, by temporarily increasing the frequency by a predetermined amount and temporarily decreasing the frequency by said predetermined amount, at different times, within a predetermined multiple of a clock cycle of the reference clock signal.
