A spread-spectrum clock (CLK) is an efficient way to reduce EMI. This article describes how the spread-spectrum CLK is defined, and provides a simple formula for estimating the EMI suppression. The resulting formula is verified by data generated by the Maxim CLK Generation chip, MAX9492. ...

AN4850 Application note STM32 MCUs spread-spectrum clock generation principles, properties and implementation Introduction The STM32F2 Series, STM32F4 Series and STM32F7 Series embed a SSCG (spread- spectrum clock generation) in their main PLL (phase-locked l...
A spread spectrum clock generation circuit (100) includes a generation means (110) configured to generate and output a spread spectrum clock based on an input reference clock, a monitoring means (130) configured to monitor a difference between the number of pulses of a reference clock input to...
SPREAD SPECTRUM CLOCK GENERATION (SSCG) By asserting the SSCG (spread spectrum clock generator) pin, PLL2 operates in spread spectrum mode, and the output frequency modulates with a triangular profile. As the clock signal energy spreads out over a range of frequencies, it reduces the peak power...
Spread spectrum clock generators. A phase lock loop generates an output clock according to a first input clock and a second input clock, a delay line is coupled between the first input clock and the phase lock loop. A modulation unit provides a modulation signal to control the delay line the...

Even without spread spectrum modulation, this level of versatility in clock generation is convenient for highly efficient multiphase switching regulator designs. Figure 2. Functional block diagram of the LTC6902 The master oscillator also drives a pseudo-random binary sequence generator block. ...
This paper proposes novel spread-spectrum clock generation (SSCG) algorithms that can select and exclude certain spectrum bands from spreading spectrum, adaptively to environmental signal functioning frequencies. This removes the need to choose certain bands for exclusion; as it is done automatically by...
