Low-Jitter, Spread-Spectrum Clock Modulators Reduce EMI in Large-Format LCD Panels

September 25, 2007 7:59 am | Product Releases | Comments

Maxim introduced its DS1081L/DS1083L 16 MHz to 134 MHz, center spread-spectrum clock modulators. These modulators use an integrated phase-locked loop (PLL) to dither the clock output around its center frequency at a user-selectable magnitude from 0 (disabled) to ±2.0 percent, thus reducing peak EMI at fundamental and harmonic frequencies. This EMI reduction is accomplished without changing clock rise/fall times or adding the space, weight, design time
