Abstract
The disclosure provides a multi-mode frequency division circuit including a frequency division factor processor, a frequency divider, and a logic operator. The frequency division factor processor receives the frequency division factor, decomposes the frequency division factor to obtain a first sub-frequency division factor and a second sub-frequency division factor, and outputs the first sub-frequency division factor or the second sub-frequency division factor according to a frequency division clock signal. The divider performs frequency division on the clock signal based on the first sub-frequency division factor or the second sub-frequency division factor to generate the frequency division clock signal. The logic operator sequentially samples the frequency division clock signal according to the rising edge and falling edge of the clock signal to generate a first signal and a second signal, and the logic operator generates an output clock signal according to the first signal, the second signal, and an indication signal.
