Product Description

The CM1453-08CP is a pi-style EMI filter array with

ESD protection, which integrates eight filters (C-L-C)

in CSP form factor with 0.40mm pitch.

Each EMI

filter channel of the CM1453-08CP is implemented as

a 3-pole L-C filter where the component values are

9.5pF-20nH-9.5pF. The roll-off frequency at -6dB

attenuation

is

380MHz

and

can

be

used

in

applications where the data rates are as high as

160Mbps while providing greater than -35dB 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

filter ports are designed and characterized to safely

dissipate

ESD

strikes

of

±15kV, 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.

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 CM1453-08CP is

ideal for EMI filtering and protecting data and control

lines for the LCD display and camera interface in

mobile handsets.

The CM1453-08CP incorporates OptiGuard

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.
