Common mode filter with ESD protection for high speed serial interface

The ECMF02-2BF3 is a highly integrated common mode filter designed to suppress EMI/RFI common mode noise on high speed differential serial buses like MIPI D-PHY, MDDI, USB2.0 and HDMI.

The ECMF02-2BF3 can protect and filter one differential lane.

Key Features

  • Very large differential bandwidth above 5 GHz
  • High common mode attenuation: - 23 dB at 900 MHz.
  • High common mode attenuation: - 20 dB between 800 MHz and 2.2 GHz.
  • Very low PCB space consumption: <1.1mm2
  • Thin package: 0.50 mm max. after reflow
  • Lead-free package
  • High reduction of parasitic elements through integration
  • Complies with the following standard:
    • IEC 61000-4-2 level 4 input and output pins:±15 kV (air discharge)±8 kV (contact discharge)
