1.1 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 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.

1.2 Features and benefits

 One, two and three differential channels common-mode EMI filters with integrated

ESD protection

 ESD protection up to 15 kV contact discharge according to IEC 61000-4-2

 Superior common-mode suppression over a wide frequency range

 Superior RF performance compared to other integrated filters or discrete filters with

external ESD protection

 Extremely high symmetry between line pairs

 Industry-standard Wafer Level Chip Scale Packages: WLCSP5, 10 and 15 for smaller

footprint

1.3 Applications

 Smartphone, cellular and cordless phone

 Tablet PC and Mobile Internet Device (MID)

 HDMI 1.4

 General-purpose EMI and Radio-Frequency Interference (RFI) filter and downstream

ESD protection
