ABSTRACT:
According to some embodiments, a frequency adjuster adjusts a frequency of an oscillator. For example, the frequency adjuster might include a plurality of capacitors that are selectable using a digital control signal, and selection logic may adjust the digital control signal based on a received indication associated with the oscillator's frequency.
