Abstract

A digital phase locked loop includes a phase acquisition unit receiving a sampled input signal and applying its output to a first input of a digital phase detector, a digital controlled oscillator producing a digital output, and a feedback path coupling the digital output of the digital controlled oscillator to a second input of the digital phase detector in the digital domain. The input signal may be sampled asynchronously.
