CM1415  
3 Channel Headset EMI Filter with ESD Protection  
Product Description  
Features  
Functionally and pin compatible with California  
Micro Device’s CSPEMI205  
Optiguardcoated for improved reliability at  
The CM1415 is a low-pass filter array integrating three  
pi-style filters (C-R-C) that reduce EMI/RFI emissions  
while at the same time providing ESD protection. This  
device is custom-designed to interface with the head-  
set port on a cellular telephone, and contains two dif-  
ferent filter values. Each high quality filter provides  
more than 30dB attenuation in the 800-2700 MHz  
range. These pi-style filters support bidirectional filter-  
ing, controlling EMI both to and from the microphone  
and speaker elements. They also support bipolar sig-  
nals, enabling audio signals to pass through without  
distortion.  
assembly  
Three channels of EMI filtering, two for earpiece  
speakers and one for a microphone  
Pi-style EMI filters in a capacitor-resistor-capacitor  
(C-R-C) network  
Greater than 30dB relative attenuation in the 800-  
2700MHz range  
+8kV ESD protection on each channel  
(IEC 61000-4-2 Level 4, contact discharge)  
+15kV ESD protection on each channel (HBM)  
8-bump, 1.41mm X 1.45mm footprint  
Chip Scale Package (CSP)  
In addition, the CM1415 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, the maximum requirement of the  
IEC 61000-4-2 international standard. Using the MIL-  
STD-883 (Method 3015) specification for Human Body  
Model (HBM) ESD, the device provides protection for  
contact discharges to greater than +15kV.  
Chip Scale Package features extremely low para-  
sitic inductance for optimum filter performance  
Lead-free version available  
Applications  
EMI filtering and ESD protection for headset micro-  
phone and speaker  
Cellular / Mobile Phones  
Notebooks and Personal Computers  
Handheld PCs / PDAs / Tablets  
Wireless Handsets  
The CM1415 is particularly well suited for portable  
electronics (e.g., cellular telephones, PDAs, notebook  
computers) because of its small package format and  
low weight.  
The CM1415 incorporates Optiguardcoating which  
results in improved reliability at assembly. The CM1415  
is available in a space-saving, low-profile Chip Scale  
Package with optional lead-free finishing.
