Abstract

See full text

Apparatus and methods for control and calibration of external oscillators are provided herein. In certain embodiments, an electronic oscillator system includes a semiconductor die and a controllable oscillator that is external to the semiconductor die. The oscillation frequency of the controllable oscillator is tuned by a first varactor and a second varactor. The semiconductor die includes a phase-locked loop (PLL) that provides fine tuning to the controllable oscillator by controlling the first varactor, and a calibration circuit that provides coarse tuning to the controllable oscillator by controlling the second varactor.
