Description
The ECMF04-4HSWM10 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, USB3.0,
Ethernet, MIPI, DisplayPort and other high-speed
serial interfaces. The device has a very large
differential bandwidth to comply with these
standards and can also protect and filter 2
differential lanes.
