In electrical systems the principal cause of electro-
magnetic interference (EMI) is the system clock
oscillator. Traditional methods of 'patching-up' systems
with too high a level of EMI is to use ferrite beads,
filters, ground planes, metal shielding and similar costly
methods, However, the most efficient and economic
method to reduce EMI is to reduce it at source: replace
the system clock ocillator with a low EMI clock oscillator.
Compared with conventional clock oscillators, Spread
Spectrum (Dithered) Oscillators can reduce EMI by as
much as 16dB. The part is a 'drop-in' replacement for a
standard clock oscillator hence there is no requirement
to re-design existing PCBs.
DESCRIPTION
EQHM572 series low EMI oscillators can reduce system EMI from 8dB
to 16dB. The oscillators are a ‘drop-in’ replacement for standard
oscillators. EMI reduction is achieved by the use of Spread Spectrum
Technology whereby the mode energy is spread over a wider
bandwidth. The modulation carrier frequency, operating in the kHz
region, makes the process transparent to the oscillator frequency.
There is a choice of modulation rates and spread to suit application
requirements.
SPREAD SPECTRUM TECHNOLOGY
Unlike a conventional clock oscillator, in a Spread Spectrum Clock
Oscillator the mode energy is spread over a wider bandwidth. This is
achieved by the frequency modulation technique. The controlled
modulation process may be applied to the 'down' side of the nominal
frequency (known as
DOWN SPREAD,)
or spread equally either side
of nominal (CENTRE
SPREAD).
Down Spread is preferred if over-
clocking would cause a problem to the system.
