ABSTRACT:
A VCO, which good temperature characteristics, high frequency accuracy, and high phase accuracy is provided as an LSI, without making its master clock frequency operate the VCO high. The VCO includes a digital VCO, a phase modulator, and a frequency band limiting element. The digital VCO outputs an oscillating frequency clock and a phase difference lower than an output cycle resolution at the same timing as the output of the oscillating frequency clock. The phase modulator makes side-band components of the output from the digital VCO move from positions near the fundamental frequency to farther bands by modulating the phase of the output from the digital VCO based on the phase difference.
