Spread-spectrum clock generator |
| 摘要 |
A spread-spectrum clock generator includes a frequency comparator, for generating a compensation signal according to a reference signal and a frequency signal corresponding to an output frequency signal; a triangle-wave generator, for generating a triangle-wave signal according to a frequency control signal; an adder, coupled between the triangle-wave generator and the frequency comparator, for adding the compensation signal to the triangle-wave signal to generate an addition result; and a frequency synthesizer, coupled between the frequency comparator and the adder, for generating the output frequency signal to adjust the output frequency signal according to the addition result so as to reduce a shift of the output frequency signal. |
