Abstract
A circuit includes: a PLL circuit which multiplies a reference clock by a multiplication factor and outputs a PLL clock; a first counter which counts up with the PLL clock for a fixed period of time; a comparator which compares a count value of the first counter with the multiplication factor; a second counter which counts up the number of times the comparison values have been matched for the fixed period of time; and an output unit which generates an enable signal when a count value of the second counter reaches the number of times the circuit waits for stability, and opens a gate to transmit the PLL clock in response to the enable signal.
