Abstract
A method is disclosed for producing an output clock signal with a target frequency using an oscillator circuit portion configured to receive a control value and produce an output clock signal with a frequency dependent on the control value. In one embodiment, the method comprises providing a first control value to the oscillator circuit portion corresponding to the target frequency, so as to cause the oscillator circuit portion to produce the output clock signal with a first frequency, comparing the output clock signal with a reference clock signal having a reference frequency to determine an offset between the first frequency and the target frequency, and providing a second control value to the oscillator circuit portion that differs from the first control value by a magnitude calculated with reference to the determined offset, to cause the oscillator circuit portion to produce the output clock signal with a second frequency.
