CM1442
LCD and Camera EMI Filter
Array with ESD Protection
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 0.40 mm pitch. The CM1442 has
component values of 15 pF − 100 W − 15 pF per channel. The CM1442
has a cut−off frequency of 120 MHz and can be used in applications
where the data rates are as high as 48 Mbps. The parts include
avalanche−type 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 ±15 kV, 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 discharges at greater
than ±30 kV.
This device is particularly well suited for portable electronics (e.g.
wireless handsets, PDAs, notebook computers) 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 OptiGuardt which results in improved
reliability at assembly. The CM1442 is available in a space−saving,
low−profile Chip Scale Package with RoHS compliant lead−free
finishing. It is manufactured with a 0.40 mm pitch and 0.25 mm CSP
solder ball to provide up to 28% board space saving versus competing
CSP devices with 0.50 mm pitch and 0.30 mm CSP solder ball.
