18EQHM53 Low EMI Oscillator

18EQHM53 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.
