Abstract
An oscillation signal with a selectable frequency is generated with a phase locked loop (). The oscillator () of the loop receives a feedback signal, to which an offset is added in order to reduce transient effects when a frequency modification is made. A first and second offset control value are used to control the offset successively. The first offset control value is controlled by a combination of the frequency settings before and after the modification. The second offset control value is controlled by the frequency settings after the modification. The first and second offset control values are used to control an offset of applying to a frequency control signal of an oscillator () of the phase locked loop (). The offset controlled by the first control offset value is applied during a predetermined time interval before the offset controlled by the second control offset value is applied.
