  • Patent number: 11962314
    Abstract: With respect to a phase locked loop (PLL) circuit that receives a first reference clock and generates an output clock, the PLL circuit includes a delay circuit that delays the first reference clock to generate a second reference clock, a feedback circuit that generates a control signal based on a phase difference between the second reference clock and a feedback clock, an oscillator that oscillates at a frequency determined based on the control signal to generate the output clock, and a divider that divides the output clock in the on state. The PLL circuit switches between a first mode and a second mode, the feedback clock in the first mode is a signal obtained by retiming an output of the divider with the output clock, and the feedback clock in the second mode is a signal obtained by retiming the first reference clock with the output clock.
