LCD and Camera EMI Filter
Array with ESD Protection
CM1430
Features
Product Description
•
•
•
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
15kV ESD protection on each channel
(IEC 61000-4-2 Level 4, contact discharge)
30kV ESD protection on each channel (HBM)
Greater than 20dB attenuation (typical) at 1 GHz
TDFN package with 0.40mm lead pitch:
• 4-ch. = 8-lead TDFN
The CM1430 is a family of pi-style EMI filter arrays
with ESD protection, which integrates four, six and
eight filters (C-R-C) in small form factor TDFN
0.40mm pitch packages. The CM1430 has
component values of 8.5pF-100Ω-8.5pF per channel.
The CM1430 has a cut-off frequency of 200MHz and
can be used in applications with data rates up to
80Mbps. 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 requirement of the

• 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
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.

Lead-free version available
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 CM1430 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 CM1430 is housed in space-saving, low-profile
8-,12- and 16-lead TDFN packages with a 0.4mm
pitch and is available with lead-free finishing. This
new small TDFN package provides up to 42% board
space savings vs. the 0.50mm pitch TDFN packages.
