1. General description
Common-mode ElectroMagnetic Interference (EMI) filters with integrated ElectroStatic Discharge
(ESD) protection for one, two and three differential channels. The devices are designed to provide
low insertion loss for differential high-speed signals on each channel while unwanted commonmode
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.
