Spread Spectrum Frequency Generation
The clocks in digital systems are typically square waves
PCBs etc. These methods are expensive. Spread
with a 50% duty cycle and as frequencies increase the
spectrum clocking reduces the peak energy by reducing
edge rates also get faster. Analysis shows that a square
the Q factor of the clock. This is done by slowly
wave is composed of fundamental frequency and
modulating
harmonics. The fundamental frequency and harmonics
ASM3P623S05/09A/B uses the center modulation spread
generate the energy peaks that become the source of
spectrum technique in which the modulated output
EMI. Regulatory agencies test electronic equipment by
frequency varies above and below the reference
measuring the amount of peak energy radiated from the
frequency with a specified modulation rate. With center
equipment. In fact, the peak level allowed decreases as
modulation, the average frequency is the same as the
the frequency increases. The standard methods of
unmodulated frequency and there is no performance

The
Timing-Safe™ technology
Timing-Safe™ technology is the ability to modulate a
clock source with Spread Spectrum technology and
maintain synchronization with any associated data path.
