CM1431  
LCD and Camera EMI Filter Array with ESD Protection  
Product Description  
Features  
Four, six and eight channels of EMI filtering with  
integrated ESD protection  
The CM1431 is a family of pi-style EMI filter arrays with  
ESD protection, which integrates four, six and eight fil-  
ters (C-R-C) in small form factor TDFN 0.40mm pitch  
packages. The CM1431 has component values of  
15pF-100Ω-15pF per channel. The CM1431 has a cut-  
off frequency of 120MHz and can be used in applica-  
tions with data rates up to 48Mbps. The parts include  
ESD diodes on every pin, which provide a very high  
level of protection for sensitive electronic components  
that may be subjected to electrostatic discharge (ESD).  
The ESD protection diodes safely dissipate ESD  
strikes of 15kV, well beyond the maximum require-  
ment of the IEC61000-4-2 international standard.  
Using the MIL-STD-883 (Method 3015) specification  
for Human Body Model (HBM) ESD, the pins are pro-  
tected for contact discharges at greater than 30kV.  
Pi-style EMI filters in a capacitor-resistor-capacitor  
(C-R-C) network  
15kV ESD protection on each channel  
(IEC 61000-4-2 Level 4, contact discharge)  
30kV ESD protection on each channel (HBM)  
Greater than 35dB attenuation (typical) at 1 GHz  
TDFN package with 0.40mm lead pitch:  
• 4-ch. = 8-lead TDFN  
• 6-ch. = 12-lead TDFN  
• 8-ch. = 16-lead TDFN  
Tiny TDFN package size:  
• 8-lead: 1.7mm x 1.35mm  
• 12-lead: 2.5mm x 1.35mm  
• 16-lead: 3.3mm x 1.35mm  
Increased robustness against vertical impacts  
during manufacturing process  
Lead-free finishing  
These devices are particularly well-suited for portable  
electronics (e.g. wireless handsets, PDAs, notebook  
computers) because of their small package and easy-  
to-use pin assignments. In particular, the CM1431 is  
ideal for EMI filtering and protecting data and control  
lines for the I/O data ports, LCD display and camera  
interface in mobile handsets.  
Applications  
LCD and Camera data lines in mobile handsets  
I/O port protection for mobile handsets, notebook  
computers, PDAs etc.  
EMI filtering for data ports in cell phones, PDAs or  
notebook computers.  
Wireless handsets  
Handheld PCs/PDAs  
LCD and camera modules  
The CM1431 is housed in space-saving, low-profile 8-,  
12- and 16-lead TDFN packages with a 0.40mm pitch  
and is available with lead-free finishing. This smaller  
size TDFN package provides up to 42% board space  
saving vs. the 0.50mm pitch TDFN packages.
