Title: Frequency synthesizer
Inventor: OKA SEIGO
IPC: H03B28/00
Filed: 1994-07-15
Abstract: PURPOSE:To reduce the spuriousness of a PLL frequency synthesizer using a direct digital synthesizer at an optional frequency. CONSTITUTION:Frequency setting signals 25 prepared beforehand for reducing the generation of the spuriousness are inputted to the direct digital synthesizer 23 and the frequency division ratio of an universal frequency divider 43 is set so as to output the signals of the frequency for which the optional frequency to be outputted from the direct digital synthesizer 23 is divided by the ratio. The output of the universal frequency divider 43 is inputted as the reference clock signal 21 of the direct digital synthesizer. Since the ratio with less spuriousness is set to the direct digital synthesizer 23 and the frequency of the reference clock signal 21 is changed corresponding to the frequency to be outputted from a PLL circuit 11, the signals with less spuriousness are outputted at any frequency.
