An analog mixed digital DLL includes a digital mode controller and an analog mode controller. The digital mode controller compares phases of delay clock signals outputted from a plurality of delay blocks and a first clock signal, detects an initial locking point, selects one delay clock signal at the detected initial locking point and controls the operation of the delay clocks. The analog mode controller compares the phase of the delay clock signal selected by the digital mode controller and the phase of a first clock signal. The analog mixed digital DLL can provide an externally inputted first control voltage or a second control voltage to the delay blocks in accordance with the digital and analog operation modes and implements a wide band frequency operation, has a short duration of jitters, prevents a multi-locking during a wide band frequency operation and decreases a current consumption.
