    Abstract: PROBLEM TO BE SOLVED: To provide a system for controlling the frequency of the output signal of a controllable oscillator (202) in a frequency synthesizer (200). SOLUTION: One such system comprises a controllable oscillator (202) and a frequency control circuit (208). The controllable oscillator (202) is configured to generate an output signal that has a predetermined frequency. The controllable oscillator (202) is also configured with a plurality of operational states that are controlled by the frequency control circuit (208). Each operational state of the controllable oscillator (202) defines a distinct frequency for the output signal of the controllable oscillator (202). The frequency control circuit (208) receives the output signal of the controllable oscillator (202) and determines the distinct frequency for the output signal that best approximates the predetermined frequency. The frequency control circuit (208) may also provide a control signal to the controllable oscillator (202) that is configured to change the controllable oscillator (202) to the operational state corresponding to the distinct frequency that best approximates the predetermined frequency.
