Abstract
Exemplary embodiments of the invention provide a reference harmonic oscillator integrated circuit having three or more terminals, with systems and methods for calibrating the harmonic oscillator to a selected first frequency using a limited number of terminals. An exemplary apparatus comprises: a reference harmonic oscillator, a first terminal to receive a supply voltage, a second terminal to receive a ground potential, a third terminal to provide an output signal having an output frequency, and may also include a fourth terminal. One of the first, second, third or fourth terminals is further adapted for input of a calibration of the first frequency. The exemplary apparatus may enter calibration and testing modes in response to various commands such as a calibration mode signal, and may also be configured through one of the terminals for output frequency selection, spread-spectrum output, and output voltage levels.
