3EQHM53 - Low EMI Oscillator

EUROQUARTZ limited

General Description

EQHM53 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.

EURO QUARTZ 5 x 3.2 x 1.2mm SMD - Group 'R' 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 3EQHM53 Low EMI Oscillator Page 1 of 2 In electrical systems the principal cause of electromagnetic 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.
