Product Description
The CM1453-04CP is a pi-style EMI filter array with
ESD protection, which integrates filters (C-L-C) in
CSP form factor with 0.40mm pitch. Each EMI filter
channel of the CM1453-04CP 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 that 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 CM1453-04CP is
ideal for EMI filtering and protecting data and control
lines for the LCD display and camera interface in
mobile handsets.
The CM1453-04CP incorporates
OptiGuard™
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.
