Abstract
The invention relates to a frequency synthesizer. An object of the invention is to provide a frequency synthesizer whose high stable performance is realized at an inexpensive cost. The frequency synthesizer includes a frequency synthesizing section generating an output signal by performing indirect frequency synthesis at a period which is equal to a product of a period of the reference signal and a first integer, and a clock generating section generating the clock signal by performing frequency synthesis for the output signal and for maintaining a frequency of the clock signal at a value which is equal to a difference between or a sum of a first frequency which is equal to a product of the frequency of the reference signal and a second integer and a second frequency indicating a number of times the phase difference is compressed.
