PURPOSE: A phase control device, a phase control print plate and a control method are provided to be capable of finely adjusting the phase of the output signal. CONSTITUTION: When the phase difference is transferred from a phase comparator(230), a charge pump(240) converts the phase difference transferred from the phase comparator to a current, and then charges the current to a capacitor(250) or discharges the current from the capacitor. Here, when the phase difference is transferred from the phase comparator as an up-signal pulse, the charge pump charges the current to the capacitor. When the phase difference is transferred from the phase comparator as a down-signal pulse, the charge pump discharges the current from the capacitor(250). The capacitor is connected to the charge pump and each of the delay units included in a voltage-controlled delay line(210). Also, the capacitor is connected to each of the delay units(110) included in a voltage-controlled delay line(100).
