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
