Praetorian III® 4, 6, 8-Channel

EMI Filter Array with ESD Protection

CM1457

Features

Functional Description

•

Four, six, or eight channels of EMI filtering

±15kV ESD protection (IEC 61000-4-2, contact

The CM1457 is an inductor-based (L-C) EMI filter array

with ESD protection, which integrates four, six, or eight

filters in a CSP form factor with 0.40mm pitch. Each EMI

filter channel of the CM1457 is implemented with the

component value of 6pF-35nH–4.7pF-35nH–1.8pF. The

cut-off frequency at -3dB attenuation is 300MHz and can

be used in applications where the data rates are as high as

160Mbps, while providing greater than -35dB attenuation

over the 800MHz to 2.7GHz frequency range. The parts

include ESD diodes on every I/O pin and provide a high

level of protection against electrostatic discharge (ESD).

The ESD protection diodes connected to the external filter

ports are designed and characterized to safely dissipate

ESD strikes of ±15kV, which is beyond the maximum

requirement of the IEC61000-4-2 international standard.

discharge) at external pins

Greater than -40dB of attenuation at 1GHz

MIL_STD_883 international ESD standard

Chip Scale Package (CSP) with 0.40mm pitch and

0.25mm CSP solder ball which features extremely

low parasitic inductance for optimum filter and

ESD performance

•

OptiGuard^TMcoating for improved reliability at

assembly

RoHS-compliant, lead-free finishing

Applications

•

LCD and camera data lines in mobile handsets

I/O port protection for mobile handsets, notebook

computers, PDAs, etc.

This device is particularly well suited for wireless handsets,

mobile LCD modules and PDAs because of its small

package format and easy-to-use pin assignments. In

particular, the CM1457 is ideal for EMI filtering and

protecting data and control lines for the LCD display and

camera interface in mobile handsets.

•

EMI filtering for data ports in cell phones, PDAs or

notebook computer

•

Wireless handsets

Handheld PCs/PDAs

LCD and camera modules

The CM1457 incorporates OptiGuardTM which results in

improved reliability at assembly. It is manufactured with a

0.40mm pitch and 0.25mm CSP solder ball to provide up to

28% board space savings vs. competing CSP devices with

0.50mm pitch and 0.30mm CSP solder ball.
