16MHz to 134MHz Spread-Spectrum  
Clock Modulator for LCD Panels  
DS1083L  
General Description  
Features  
The DS1083L is a spread-spectrum clock modulator IC  
that reduces EMI in high-clock, frequency-based, digi-  
tal electronic equipment.  
Modulates a 16MHz to 134MHz Clock with Center  
Spread-Spectrum Dithering  
Selectable Spread-Spectrum Modulation  
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 frequen-  
cy at a pin-selectable magnitude. The DS1083L auto-  
matically adjusts the dither rate based on the input  
clock frequency to maximize the EMI reduction.

Low 7.ps Cycle-to-Cycle Jitter  
Automatic Dither Cycle Rate Adjustment to  
By dithering the system clock, all the address, data,  
and timing signals generated from this signal are also  
dithered so that the measured EMI at the fundamental  
and harmonic frequencies is greatly reduced. This is  
accomplished without changing clock rise/fall times or  
adding the space, weight, design time, and cost asso-  
ciated with mechanical shielding.
