Common-mode filter and ESD protection for USB 2.0 and MIPI/MDDI interfaces

The device 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 or USB 2.0.

Also it can protect and filter one differential lane.

Key Features

  • High common mode attenuation:
    • -34 dB at 900 MHz
    • -20 dB between 800 MHz and 2.2 GHz
  • Large bandwidth: 1.7 GHz
  • Very low PCB space consumption
  • Thin package: 0.55 mm max.
  • RoHS package
  • High reduction of parasitic elements through integration
