Secure Digital (SD) Card EMI Filter  
Array with ESD Protection  
CM1423  
Features  
Product Description  
•
Provides EMI filtering and ESD protection for an  
SD port on a mobile device  
Six channels of EMI filtering with ESD protection  
Four channels of ESD protection  
15kV ESD protection on all I/O pins (IEC 61000-  
4-2, contact discharge)  
The CM1423 is an EMI filter array with ESD  
protection, which integrates six Pi- filters (C-R-C) and

•
four channels of ESD protection. The CM1423’s  
filters have component values of 12pF-100Ω-12pF.  
The part includes ESD protection diodes on every  
pin, which provide a very high level of protection for  
sensitive electronic components that may be  
subjected to electrostatic discharge (ESD). All the  
ESD diodes safely dissipate ESD strikes of 15kV,  
•
•
30kV ESD protection (HBM)  
Better than 25dB of attenuation at 1GHz for  
12pF-100Ω -12pF filter configuration  
Integrates 34 components into small form factor  
CSP solution  
20-bump, 4.000mm x 1.458mm footprint  
Chip Scale Package  
Chip Scale Package features extremely low  
lead inductance for optimum filter and ESD  
performance

•
•
beyond 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 pins are protected for contact  
discharges at greater than 30kV.  
•
•
Available with OptiGuard™ coating for improved  
reliability at assembly  
RoHS compliant (lead-free) finishing  
This device is particularly well-suited for portable  
electronics (e.g. mobile handsets, PDAs, notebook  
computers) because of its small package and easy-  
to-use pin assignments. In particular, the CM1423 is  
ideal for EMI filtering and protecting data lines from  
ESD for the Secure Digital (SD) Card interface slot in  
mobile handsets. The CM1423 is an all-inclusive  
solution for the SD card interface since its EMI filters  
provide the proper cut-off frequency to attenuate  
unwanted signals.  
Applications  
•
Secure Digital (SD) card data lines in mobile  
handsets  
SD card interface protection for other mobile  
electronics such as MP3 players, PDAs and  
digital cameras  
I/O port protection for mobile handsets, notebook  
computers, PDAs etc.  
EMI filtering for data ports in cell phones, PDAs  
or notebook computers.  
•
•
•
The CM1423 is manufactured in a space-saving, low-  
profile, chip-scale package, and is optionally  
available with OptiGuard™ coating for improved  
reliability. It is available with RoHS compliant lead-  
free finishing.
