CM1690
Praetorian
L-C LCD and
Camera EMI Filter Array
with ESD Protection
Product Description
The CM1690 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 mDFN 0.40 mm pitch packages. Each EMI filter
channel of the CM1690 is implemented as a 3−pole L−C filter where
the component values are 16 pF − 12 nH − 16 pF. The CM1690’s
roll−off frequency at –6 dB attenuation is 330 MHz and can be used in
applications where the data rates are as high as 140 Mbps while
providing greater than −35 dB attenuation over the 1.0 GHz to
3.0 GHz 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 ±15 kV, 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 wireless handsets, mobile
LCD modules and PDAs because of its small package format and
easy−to−use pin assignments. In particular, the CM1690 is ideal for
EMI filtering and protecting data and control lines for the LCD display
and camera interface in mobile handsets.
The CM1690 is available in space saving, ultra low profile 8−, 12−,
and 16−lead 0.40 mm mDFN packages with lead−free finishing.
