Abstract
A digital phase locked loop includes a phase acquisition unit for producing a digital representation of the phase of a reference signal, a digital phase detector having a first input receiving a digital signal from, or derived from, the output of the phase acquisition unit, digital loop filter filtering the output of the digital phase detector, and a digital controlled oscillator generating an output signal under the control of the digital loop filter. A digital feedback loop provides a second input to the digital phase detector from the output of the digital controlled oscillator.
