LCD and Camera EMI Filter Array
with ESD Protection
CM1442
Features
Product Description
•
The CM1442 is a family of pi-style EMI filter arrays
with ESD protection, which integrates six and eight
filters (C-R-C) in Chip Scale Package form factor with
0.40mm pitch. The CM1442 has component values of
15pF-100Ω-15pF per channel. The CM1442 has a
cut-off frequency of 120MHz and can be used in
applications where the data rates are as high as
48Mbps. The parts include avalanche-type 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
requirement of the IEC61000-4-2 international
standard. Using the MIL-STD-883 (Method 3015)
specification for Human Body Model (HBM) ESD, the
pins are protected for contact discharges at greater
than ±30kV.

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
This device is particularly well suited for portable
electronics (e.g. wireless handsets, PDAs, notebook
computers) because of its small package format and
easy-to-use pin assignments. In particular, the
CM1442 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 CM1442 incorporates OptiGuard™ which results
in improved reliability at assembly. The CM1442 is
available in a space-saving, low-profile Chip Scale
Package with optional lead-free finishing. It is
manufactured with a 0.40mm pitch and 0.25mm CSP
solder ball to provide up to 28% board space saving
versus competing CSP devices with 0.50mm pitch
and 0.30mm CSP solder ball.
