摘要
A phase lock loop to control phase error from a first input signal and a second input signal including a phase error detector to detect a phase error signal between the first input signal and the second input signal at a predetermined rate, a down-sampling circuit to down-sample the phase error signal and to output a down-sampled signal at a reduced rate with respect to the predetermined rate, a loop filter to filter the down-sampled signal to obtain a filtered signal, and an up-sampling circuit to up-sample the filtered signal at the predetermined rate.
