2 Channel Headset EMI Filter with ESD Protection

Product Description

Functionally and pin compatible with CMD’s

The CM1414 is a low-pass filter array designed specifi-

cally to reduce EMI/RFI emissions and provide ESD

protection for a headset port on a cellular and mobile

devices. The CM1414 integrates two high quality, pi-

style filters (C-R-C) filters, one for a microphone and

one for an earpiece or speaker, each providing more

than 35dB attenuation relative to the pass band attenu-

ation in the 800-2700 MHz range. These filters support

bidirectional filtering, reducing EMI both to and from

the headset port and support bipolar audio signals

without distortion.

OptiGuard™ coated for improved reliability at

Two channels of EMI filtering, one for a micro-

phone and one for an earpiece speaker

Pi-style EMI filters in a capacitor-resistor-capacitor

(C-R-C) network

Greater than 35dB attenuation in the 800-

2700MHz range

+8kV ESD protection on each channel (IEC 61000-

4-2 Level 4, contact discharge)

In addition, the CM1414 provides a very high level of

protection for sensitive electronic components that may

be subject to electrostatic discharge (ESD). The input

pins are designed and characterized to safely dissipate

ESD strikes of +8kV contact discharge, the maximum

requirement of the IEC 61000-4-2 international stan-

dard. Using the MIL-STD-883 (Method 3015) specifica-

tion for Human Body Model (HBM) ESD, the device

provides protection for contact discharges to greater

than +15kV. The CM1414 protects sensitive compo-

nents such as CPU and DSPs that have much weaker

internal ESD protection circuitry usually only intended

for mechanical handling protection.

Applications

•

EMI filtering and ESD protection for headset micro-

phone and earpiece speaker ports

Cellular / Mobile Phones

Notebooks and Personal Computers

Handheld PCs / PDAs / Tablets

Wireless Handsets

•

The CM1414 is particularly well suited for portable

electronics because of its small package format and

low weight. The CM1414 incorporates OptiGuard™

coating which results in improved reliability at assem-

bly and is available in a space-saving, low-profile Chip

Scale Package with optional lead-free finishing.
