Praetorian® L-C LCD and Camera
EMI Filter Array with ESD Protection
CM1690
Features
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 uDFN
0.40mm pitch packages. Each EMI filter channel of
the CM1690 is implemented as a 3-pole L-C filter
where the component values are 16pF-12nH-16pF.
The CM1690's roll-off frequency at –6dB attenuation
is 330MHz and can be used in applications where the
data rates are as high as 140Mbps while providing
greater than -35dB attenuation over the 1.0GHz to
3.0GHz 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.

• 6-channel = 12-lead uDFN
• 8-channel = 16-lead uDFN
Tiny uDFN package size:
• 8-lead: 1.70mm x 1.35mm
• 12-lead: 2.50mm x 1.35mm
• 16-lead: 3.30mm x 1.35mm

Applications
•
•
•
LCD and camera data lines in mobile handsets
Wireless handsets
LCD and camera modules
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 0.40mm uDFN packages
with lead-free finishing.
