Abstract: The present disclosure provides a method and a phase lock detection apparatus for detecting whether a phase of an output signal is locked to the phase of a reference signal. The apparatus includes a first divider that individually frequency-divides first and second pulse signals, a phase frequency detector that outputs third and fourth pulse signals that correspond to a phase difference between the frequency-divided first and second pulse signals, a second divider that individually frequency-divides the third and fourth pulse signals, and a determiner that determines whether a phase of the second pulse signal is locked, based on the frequency-divided third and fourth pulse signals.
