General Description
The DS1083L is a spread-spectrum clock modulator IC that reduces EMI in high-clock, frequency-based, digital electronic equipment.
Using an integrated phase-locked loop (PLL), the DS1083L accepts an input clock signal in the range of 16MHz to 134MHz and delivers a spread-spectrum modulated output clock signal. The PLL modulates, or dithers, the output clock about the center input frequency at a pin-selectable magnitude. The DS1083L automatically adjusts the dither rate based on the input clock frequency to maximize the EMI reduction.
