Abstract
A phase-locked loop includes a phase detection unit configured to compare the phase of a feedback clock with the phase of an input clock, a clock generation unit configured to adjust the frequency of a first clock based on a result of the comparison of the phase detection unit, a first division unit configured to generate an output clock by dividing the first clock at a first division ratio in test mode and generate the output clock by dividing the first clock at a second division ratio that is lower than the first division ratio in normal mode, and a second division unit configured to generate the feedback clock by dividing the output clock.
