Abstract:
Methods and systems to provide digitally controlled crystal oscillators are disclosed. One example method includes determining a state of an oscillator system and selecting a first output of a digitally controlled crystal oscillator or a second output of a second oscillator based on the determination. In an example implementation, the second oscillator is a ring oscillator.
