Abstract
In generating a frequency-modulated clock, a first frequency modulation (FM) signal having frequency fm is frequency-modulated by a second FM signal having a second frequency fm , generating a clock modulation signal fm . The clock generation signal fm is used to frequency-modulate the system clock CLK by the clock modulation signal fm . Thus, the spectrum of the clock is doubly dispersed by the first and the second FM frequencies. As a result, peak levels at the fundamental and higher harmonic frequencies are reduced as compared with conventional clock generation device.
