3EQHM8

      3EQHM8 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.
      The main field of 3EQHM8 are (1)Printers, Multiple Function Printers (MPCs);(2)Digital Copiers; PDAs.(3)Networking: LAN/WAN; Routers.(4)Storage Systems (CD-ROM, VCD, DVD, HDD)(5)Scanners; Modems; Projectors.(6)Embedded Systems;(7)Musical Instruments;(8)Automotive: GPS car navigation systems;(9)LCD PC Monitors; LSD TVs;(10)ADSL;PCMCIA;(11)Still Digital Cameras (SDCs).
