Abstract:
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.
