CM1409
LCD and Camera EMI Filter
Array with ESD Protection
Product Description
The CM1409 is a family of pi−style EMI filter arrays with ESD
protection, which integrates either six or eight filters (C−R−C) in
a small form factor, WDFN 0.50 mm pitch package. The CM1409 has
component values of 15 pF
−
100
W
−
15 pF per channel. The CM1409
has a cut−off frequency of 110 MHz and can be used in applications
with data rates up to 44 Mbps. The parts include ESD diodes on every
pin, which provide a very high level of protection for sensitive
electronic components against electrostatic discharge (ESD).
The ESD protected diodes safely dissipate ESD strikes of
±15
kV,
which even exceeds 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.
These devices are particularly well−suited for portable electronics
(e.g. wireless handsets, PDAs, notebook computers) because of their
small package and easy−to−use pin assignments. In particular,
the CM1409 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 CM1409 is housed in space−saving, low−profile 12− and
16−lead WDFN packages with a 0.50 mm pitch, RoHS−compliant,
lead−free finishing.
