ABSTRACT:
A phase-locked loop circuit includes a phase comparator for comparing a phase of an input signal with a reference input, connecting circuits having circuit elements arranged in signal paths to be selectively operative, output circuit for supplying an output of the phase comparing means to the connecting circuits, and control circuit located between the output circuit and phase comparator for making a signal path operative by controlling the output circuit.
