Abstract

A device includes a digitally controlled oscillator and an interpolator having a data input and a data output coupled to the digitally controlled oscillator. The interpolator may be configured to receive an oscillator control signal at the data input and to provide an interpolated oscillator control signal at the data output. An interpolation rate of the interpolator may depend on the oscillator control signal. Alternatively, a device can include a digitally controlled oscillator having a control input, a sampling unit coupled to the control input of the digitally controlled oscillator, and a timing error detector coupled to an output of the digitally controlled oscillator. The sampling rate of the sampling unit can depend on an output of the timing error detector.
