Product Description
The CM1460 is a family of pi-style EMI filter arrays
with ESD protection, which integrates four, six and
eight filters (C-L-C) in small form factor TDFN
0.50mm pitch packages. Each EMI filter channel of
the CM1460 is implemented as a 3-pole L-C filter
where the component values are 15pF-17nH-15pF.
The CM1460's roll-off frequency at -6dB attenuation
is 350MHz and can be used in applications where the
data rates are as high as 140Mbps while providing
greater than 30dB over the 800MHz to 2.7GHz
frequency range.
The parts include 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 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 CM1460 is ideal for
EMI filtering and protecting data and control lines for
the LCD display and camera interface in mobile
handsets.
The CM1460 is housed in space saving, low profile,
0.50mm pitch TDFN packages and is available in
lead-free format.
