EQHM8 Group ‘R’ Low EMI Oscillators

8 pin Dual-in-Line Spread Spectrum Clock Ocillator

Page 1 of 2

Provides up to 15dB reduction in system EMI

‘Drop-in’ replacement for standard clocks

Choice of modulation rate and spread

Miniature package: 5.0 mm x 3.2 mm x 1.2mm

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.

DESCRIPTION

EQHM8 series low EMI oscillators can reduce system EMI by 15dB.

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.

Compared with conventional clock oscillators, Spread

Spectrum (Dithered) Oscillators can reduce EMI by as

much as 15dB. The part is a 'drop-in' replacement for a

standard clock oscillator hence there is no requirement

to re-design existing PCBs.

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.
