Patent ID: 8466752

Claim:
An oscillator circuit comprising: a first pad associated with a first terminal of an oscillator; a second pad associated with a second terminal of the oscillator, the oscillator configured generate an oscillating signal and communicate the oscillating signal from the second terminal to a clock distributor coupled to the second pad; an oscillator gain element comprising an output node coupled to the first pad and an input node coupled to the second pad, the gain element configured to control a frequency of the oscillating signal generated by the oscillator when the oscillator comprises a resonator; a digital-to-analog converter (DAC) coupled to the first pad and configured to control the frequency of the oscillating signal when the oscillator comprises a voltage controlled oscillator module; and a switching circuit coupled to the gain element and configured to: enable the gain element when the oscillator comprises a resonator; and disable the gain element when the oscillator comprises a voltage controlled oscillating module.
