3EQHM53, Low EMI Oscillator

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.

Traditional methods of 'patching-up' systems with too high a level of EMI is to use ferrite beads, filters, ground planes, metal shieldin
