摘要：
A lock-on detection circuit for a phase-locked loop includes circuitry configured to receive first up and down outputs and second up and down outputs from one or more phase detectors and to determine from the first up and down outputs and the second up and down outputs how well the phase-locked loop is locked on to a reference clock.
