The invention discloses a frequency phase controller. At least one frequency phase control component is arranged in a complex programmable logic device CPLD and comprises a phase control word register, a first adder and a comparator, wherein the phase control word register is connected with the input end of the first adder which is connected with the input end of the comparator, the phase controlword register is used for storing input phase control words and outputting the phase control words to the first adder, the first adder is used for performing add operation for frequency control data and the phase control words and then transmitting to the comparator, and the comparator is used for performing duty ratio adjustment for the output signals of the first adder according to the threshold value of the input reference voltage.
