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.
