Digital phase-locked loop |
摘要 |
A digital phase-locked loop with a digitally controlled oscillator is disclosed. The phase difference between a reference phase and a phase derived from the output phase of the oscillator is determined by a phase detector device and converted into a corresponding digital set value. The digital set value from the phase detector device is fed through a digital filter, to the digitally controlled oscillator, for the corresponding setting of the output phase thereof. By means of the above architecture any digital loop filter may be used.
