Product Description
California Micro Devices' 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 chan-
nel 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 fre-
quency 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 dis-
charges at greater than ±30kV.
This device is particularly well suited for wireless hand-
sets, mobile LCD modules and PDAs because of its
small package format and easy-to-use pin assign-
ments. In particular, the CM1460 is ideal for EMI filter-
ing 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 8,
12 and 16-lead TDFN packages where the pitch is
0.50mm and is available in lead-free format.
