Description
August 2014
This is information on a product in full production.
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 Full HD, MIPI, Display Port and
other high speed serial interfaces.The device has
a very large differential bandwidth to comply with
these standards. The device can protect and filter
2 differential lanes.
