Abstract
A first frequency accumulator () operates using an output signal of a variable frequency divider () as a clock. A second frequency accumulator () operates using a reference signal from a reference signal source () as a clock. A comparison operating circuit () compares the output values of the first frequency accumulator () and the second frequency accumulator (), and calculates a parameter so that a result of the comparison falls within a set value. A digital-analog converter () outputs a signal to be added to an output of a loop filter () depending on the parameter output from the comparison operating circuit ().
