Datasheet
1. Product profile
1.1 General description
The devices are common-mode ElectroMagnetic Interference (EMI) filters with integrated
ElectroStatic Discharge (ESD) protection for two and three differential channels. The
devices are designed to provide low insertion loss for differential high-speed signals on
each channel while unwanted common-mode signals are attenuated.
Each differential channel incorporates two signal lines that are coupled by integrated coils.
Diodes provide protection to downstream components from ESD voltages up to 15 kV on
each signal line.
