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.

(C-R-C) network

(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.
