CM1431
LCD and Camera EMI Filter Array with ESD Protection
Features
Four, six and eight channels of EMI filtering with
integrated ESD protection
Pi-style EMI filters in a capacitor-resistor-capacitor
(C-R-C) network

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

Product Description
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.
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.
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.
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
