General Description
The DS1083L is a spread-spectrum clock modulator IC
that reduces EMI in high-clock, frequency-based, digi-
tal 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 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.
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.
The DS1083L is provided in a low-cost, space-saving,
6-lead thin SOT23 package and operates over a full
automotive temperature range of -40°C to +125°C.
