ABSTRACT:
The present invention discloses a delay-locked loop device capable of anti-false-locking, which comprises: a voltage control delay circuit comprising a plurality of delay units in a series for generating a delayed phase according to a reference phase and a control voltage; a phase detector coupled to the voltage control delay circuit for generating a control signal according to a lock indication signal, the reference phase, and the delayed phase; a charge pump coupled to the phase detector for transmitting the control voltage to the voltage control delay circuit according to the control signal; and a lock detector coupled to the voltage control delay circuit for generating the lock indication signal for the phase detector according to output phases of at least one delay unit of the voltage control delay circuit.
