APPARATUS AND METHOD FOR PERFORMING SPREAD-SPECTRUM CLOCK CONTROL |
摘要 |
A terminal includes control logic to control a phase-locked loop to output a spread-spectrum clocking signal. The control logic controls the generation of the spread-spectrum clocking signal by adjusting at least one parameter of the phase-locked loop. The parameter may be a charge pump setting or a loop-filter capacitance of the phase-locked loop, or their digital equivalents. Adjustment of the parameter reduces a predetermined portion of a communications spectrum. The predetermined portion may be located within a range of frequencies allocated to a specific channel, and reduction of the spectrum in this range may serve to reduce noise associated with clocking harmonics. |
