EMI4182
Common Mode Filter with
ESD Protection
Functional Description
The EMI4182 is an integrated common mode filter providing both
ESD protection and EMI filtering for high speed digital serial
interfaces such as HDMI or MIPI D-PHY.
The EMI4182 provides protection for two differential data line pairs
in a small RoHS-compliant WDFN10 package.
Features
• Highly Integrated Common Mode Filter (CMF) with ESD Protection
provides protection and EMI reduction for systems using High Speed
Serial Data Lines with cost and space savings over discrete solutions
• Large Differential Mode Bandwidth with Cutoff Frequency > 2 GHz
• High Common Mode Stop Band Attenuation: >25 dB at 700 MHz,
>30 dB at 800 MHz
• Provides ESD Protection to IEC61000-4-2 Level 4, ±15 kV Contact
Discharge
• Low Channel Input Capacitance Provides Superior Impedance
Matching Performance
• Low Profile Package with Small Footprint in WDFN10 2 x 2.5 mm
Pb−Free Package
• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS
Compliant
Applications
• HDMI/DVI Display in Mobile Phones
• MIPI D-PHY (CSI-2, DSI, etc) in Mobile Phones and Digital Still
Cameras

ESD Voltage Clamping
For sensitive circuit elements it is important to limit the voltage that an IC will be exposed to during an ESD event to as low
a voltage as possible. The ESD clamping voltage is the voltage drop across the ESD protection diode during an ESD event per
the IEC61000−4−2 waveform. Since the IEC61000−4−2 was written as a pass/fail spec for larger systems such as cell phones
or laptop computers it is not clearly defined in the spec how to specify a clamping voltage at the device level. ON Semiconductor
has developed a way to examine the entire voltage waveform across the ESD protection diode over the time domain of an ESD
pulse in the form of an oscilloscope screenshot, which can be found on the datasheets for all ESD protection diodes. For more
information on how ON Semiconductor creates these screenshots and how to interpret them please refer to On Semiconductor
Application Notes AND8307/D and AND8308/D.
