  • Phase-locked loop circuit and digital operation system
    Patent number: 11757456
    Abstract: Disclosed is a phase-locked loop circuit, including: a phase-locked loop, a locking detection circuit, an input end for inputting a reference clock signal, a first output end for outputting an oscillator clock signal, and a second output end for outputting a locking signal, wherein the phase-locked loop is configured to output the oscillator clock signal according to the reference clock signal and control the reference clock signal and the oscillator clock signal to be synchronous; and the locking detection circuit is configured to output the locking signal to the second output end when the oscillator clock signal and the reference clock signal are synchronous.
    Type: Grant
