Common-mode filter and ESD protection for MIPI D-PHY and MDDI interfaces

The ECMF04-4AMX12 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 or MDDI.

The ECMF04-4AMX12 can protect and filter 2 lanes.

Key Features

  • Very large differential bandwidth > 6 GHz
  • High common mode attenuation:
    • -34 dB at 900 MHz
    • -20 dB between 800 MHz and 2.2 GHz
  • Very low PCB space consumption
  • Thin package: 0.6 mm max
  • Lead-free package
  • High reduction of parasitic elements through integration
  • Complies with the following standards:
    • IEC 61000-4-2 level 4 input and output pins:±15 kV (air discharge)±8 kV (contact discharge)
