ECMF: ST common-mode filters with integrated ESD protection
for high-speed interfaces
ST ECMF technology ensures deep, ultrawide attenuation of common-mode noise at WLAN and Bluetooth frequencies (2.4 to 6 GHz), along with robust (+10 kV) contact discharge ESD protection. Featuring 10.7 GHz bandwidth, these new filters comply with latest high-speed standards, including USB4, HDMI 2.1 and USB 3.2. The devices come in tiny 6- and 10-lead µQFN packages and are optimized for personal electronics and industrial applications.
Using integrated common-mode filters in industrial automation and computer applications
New ST common-mode filters with an extremely wide 10.7 GHz differential bandwidth to protect antenna sensitivity in adjacent wireless circuitry from the latest serial digital interfaces.
We explain how differential lines can generate electromagnetic noise that can affect the receiver sensitivity, and how to maintain noise-free reception of RF signals.
