1.1. General description
ElectroStatic Discharge (ESD) protection for one, two and three differential channels.
The devices are footprint compatible to PCMFxUSB3B/C common mode filters with ESD
protection.
Diodes provide protection to downstream components from ESD voltages up to ±20 kV on each
signal line.
