  • PHASE SYNCHRONICATION CIRCUIT AND TELEVISION SIGNAL RECEPTION CIRCUIT
    Publication number: 20130063661
    Abstract: A phase synchronization circuit includes a low-pass filter configured to integrate the pulse signal output from a charge pump, and a line filter configured to be provided on a control voltage supply line for supplying the control voltage from the low-pass filter to a voltage controlled oscillation circuit. Here, one end of a capacitor of the line filter is connected, through resistance of a CP current switching circuit, from an output terminal of the charge pump to the ground in terms of high frequencies.
