A circuit for eliminating clock jitter based on reconfigurable multi-phase-locked loops includes multiple phase-locked loops, a data selector and a signal synthesizer. In a case of generating a clock signal with low jitter, output signals of two phase-locked loops are adjusted to be the same in frequency and phase, and output signals of other phase-locked loops are adjusted to be different from each other in frequency. The data selector selects output signals, and the signal synthesizer is enabled to superimpose and then average the first and second selected output signals, so as to obtain a clock signal with jitter eliminated. In a case of generating multiple clock signals with different frequencies, output signals of the multiple phase-locked loops are adjusted to be different from each other in frequency, to obtain multiple clock signals with different frequencies through the data selector without enabling the signal synthesizer.
