PCMFxUSB3BA/C seriesCommon-mode EMI filter for differential channels withintegrated bidirectional ESD protectionRev. 2 — 14 August 2019Product data sheet1. General description Common-mode ElectroMagnetic Interference (EMI) filters with integrated bidirectional ElectroStatic Discharge (ESD) protection for one, two and three dif erential channels. The devices are designed to provide low insertion loss for dif erential high-speed signals on each channel while unwanted common-mode signals are attenuated. Each dif erential 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.
