CM1423  
Secure Digital (SD) Card EMI Filter Array with ESD Protection  
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

4-2, contact discharge)  
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  
Available with OptiGuard™ coated version for  
improved reliability at assembly  
Lead-free version available  
California Micro Devices's CM1423 is an EMI filter  
array with ESD protection, which integrates six Pi- fil-  
ters (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 protec-  
tion for sensitive electronic components that may be  
subjected to electrostatic discharge (ESD). All the  
ESD diodes are designed and characterized to safely  
dissipate ESD strikes of 15kV, beyond 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 pins are  
protected for contact discharges at greater than 30kV.

This device is particularly well suited for portable elec-  
tronics (e.g. mobile handsets, PDAs, notebook com-  
puters) because of its small package format 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 solu-  
tion for the SD card interface since its EMI filters pro-  
vide 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 elec-  
tronics 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  
also available with lead-free finishing.
