Common mode filter with ESD protection

This device is a highly integrated common mode filter designed to suppress EMI/RFI common mode noise on high speed differential serial buses like HDMI 2.0, HDMI1.4, USB 3.1 Gen 1, Ethernet, MIPI, Display Port and other high speed serial interfaces. It has a very large differential bandwidth to comply with these standards and can also protect and filter 2 differential lanes.

Key Features

  • 5GHz differential bandwidth to comply with HDMI 2.0, HDMI 1.4, USB 3.1, MIPI, Display Port, etc.
  • High common mode attenuation on LTE, GSM, GPS and WLAN frequencies:
    • -13 dB at 0.7 GHz
    • -23 dB at 1.5 GHz
    • -25 dB at 2.4 GHz
    • -23 dB at 2.7 GHz
    • -13 dB at 5.0 GHz
  • Very low PCB space consumption
  • Thin package: 0.5 mm max
  • Lead free and RoHS package
  • High reduction of parasitic elements through integration
