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 applica-

tions 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 sensi-

tive 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 dis-

charges at greater than ±30kV.

This device is particularly well suited for portable elec-

tronics (e.g. wireless handsets, PDAs, notebook com-

puters) 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

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 manu-

factured 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.
