Features  
4-, 6- and 8-Channel Series Inductor Networks  
Product Description  
Ultra-low capacitance filter results in excellent sig-  
nal integrity  
CMD’s CM1470 is a family of series inductor networks  
providing EMI filtering for applications that are  
sensitive to signal integrity such as high-resolution  
camera interfaces. The CM1470 is configured in 4, 6  
and 8 channel formats. Each channel is implemented  
as a single inductor element where the component  
value is 17nH. The CM1470 will help suppress EMI  
radiation to the external environment. The parts  
integrate ESD diodes on every pin to provide  
protection during the manufacturing process when the  
device is placed on the PCB from a pick-and-place  
machine. The ESD protection diodes safely dissipate  
ESD strikes of 2kV, per the MIL-STD-883 (Method  
3015) specification for Human Body Model (HBM)  
ESD.

Applications  
This device is particularly well suited for portable  
electronics (e.g. wireless handsets, PDAs) because of  
its small package format and easy-to-use pin  
assignments. In particular, the CM1470 is ideal for EMI  
filtering data and control lines in camera modules  
where it is placed near the transmission source on a  
flexible PCB. The CM1470 level of performance (i.e.  
cutoff frequency and attenuation level) can be tuned  
with external signal trace capacitance.  
Data and control lines for high resolution camera  
modules in phones  
LCD modules  
Mobile handsets  
High-speed data I/O lines  
The CM1470 incorporates OptiGuardwhich results in  
improved reliability at assembly. The CM1470 is avail-  
able in a space-saving, low-profile Chip Scale Package  
with lead-free finishing.
