CM1407  
4 and 8 Channel EMI Filter Arrays with ESD Protection  
Product Description  
Features  
Four and eight channels of EMI filtering with ESD  
California Micro Devices's CM1407 is an EMI filter  
array with ESD protection, which integrates either four  
or eight pi filters (C-R-C). The CM1407 has component  
values of 7.5pF-200-7.5pF. The parts include ESD  
protection diodes on every pin, providing a very high  
level of protection for sensitive electronic components  
that may be subjected to electrostatic discharge (ESD).  
The ESD diodes connected to the filter ports safely dis-  
sipate ESD strikes of 15kV contact discharge, twice  
the specification requirement of the IEC 61000-4-2,  
Level 4 international standard. Using the MIL-STD-883  
(Method 3015) specification for Human Body Model  
(HBM) ESD, the pins are protected for contact dis-  
charges at greater than 30kV.  
protection  
Greater than 25dB of attenuation from 800MHz  
to 3GHz  
15kV ESD protection (IEC 61000-4-2, contact  
discharge)  
30kV ESD protection (MIL-STD-883, Method  
3015, HBM)  
Fabricated with Centurion™ advanced low capaci-  
tance zener process technology  
Space saving, low profile 8 and 16-lead TDFN  
packages  
Lead-free version available  
Applications  
This device is particularly well-suited for portable elec-  
tronics (e.g. mobile handsets, PDAs, notebook com-  
puters) because of its small package and easy-to-use  
pin assignments. In particular, the CM1407 is ideal for  
EMI filtering and protecting data lines from ESD in  
wireless handsets.  
I/O port protection for mobile handsets, notebook  
computers, PDAs etc.  
EMI filtering for data ports in cell phones, PDAs or  
notebook computers.  
EMI filtering for LCD, camera and chip-to-chip data  
lines  
The CM1407 is available in space-saving, low-profile,  
8 and 16-lead TDFN packages. It is fabricated with  
California Micro Devices' Centurionprocess and  
available with optional lead-free finishing.
