1. A method of generating an oscillating signal having a target frequency from an oscillator having a mechanical resonator, the oscillator being coupled to a circuit to provide the oscillating signal to the circuit, the method comprising:
- providing, from the oscillator to the circuit, at least one value indicative of a frequency of the oscillator and/or the mechanical resonator;
generating a first tuning signal having a first value, wherein the first tuning signal is generated in response to receiving the at least one value;
applying to the oscillator, from the circuit, the first tuning signal having the first value;
applying to the oscillator, from the circuit, an automatic frequency control (AFC) tuning signal having a second value different than the first value;
receiving, at the circuit, the oscillating signal from the oscillator; and
synthesizing, using a frequency synthesizer, a synthesized signal having a synthesized frequency different than a frequency of the oscillating signal.

Abstract
Systems and methods for operating with oscillators configured to produce an oscillating signal having an arbitrary frequency are described. The frequency of the oscillating signal may be shifted to remove its arbitrary nature by application of multiple tuning signals or values to the oscillator. Alternatively, the arbitrary frequency may be accommodated by adjusting operation one or more components of a circuit receiving the oscillating signal.
