Abstract
Disclosed is a frequency synthesizer including first and second shift register circuitsandeach for outputting PLL setting data on a rising edge of a load enable signal, first and second fractional modulatorsandeach for generating dividing number control data on the basis of the PLL setting data in synchronization with a reference signal, and first and second fractional PLL synthesizersandeach for generating a high frequency signal according to the PLL setting data, the reference signal, and the dividing number control data. By controlling the timing of the load enable signal, the frequency synthesizer carries out phase control between the high frequency signals generated by the first and second fractional PLL synthesizersand
