PROBLEM TO BE SOLVED: To provide a PLL device which shortens a lock-up time, reduces power consumption and can be easily made by using LSI. SOLUTION: This device is provided with a generating means 2 for generating the plural reference signals of different phases, a variable frequency divider 17 for dividing the frequency of an output signal from a voltage controlled oscillator 16, a distributing means for distributing the output of the variable frequency divider and phase comparators 7-10 for comparing the phases of respective feedback signals outputted by the variable frequency divider 17 and the distributing means 18 with the phases of respective reference signals and outputting plural phase comparing signals.
