摘要
An oscillator 10 with a noise reduction function has a memory 80 that memorizes modulation data DM for performing the spread spectrum modulation input from an output terminal fout, a modulation signal output circuit 60 that generates a modulation signal SM from the modulation data DM memorized in the memory 80, and a mixer 53 that overlays the modulation signal SM on the control voltage VC of a voltage control oscillator (VCO) 54 of a PLL circuit 50, and it becomes possible to output a spread spectrum modulated output signal CLv under a specification desired by a user by memorizing in the memory 80 the modulation data DM that corresponds to the spread spectrum modulation the user tries to set.
