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)
 USB 3.1, USB 2.0, HDMI 2.0, HDMI 1.4
 MIPI M-PHY and D-PHY as used in Camera Serial Interface (CSI) and Display Serial
Interface (DSI)
 General-purpose EMI and Radio-Frequency Interference (RFI) filter and downstream
ESD protection
