CM1690
Praetorian™ L-C LCD and Camera EMI Filter Array
with ESD Protection in Ultra-Thin uDFN Packages
Features
• Four, six and eight channels of EMI filtering with
integrated ESD protection
• Pi-style EMI filters in a capacitor-inductor-capacitor
(C-L-C) network
• ±15kV ESD protection on each channel
(IEC 61000-4-2 Level 4, contact discharge)
• ±30kV ESD protection on each channel (HBM)
• Greater than -35dB attenuation (typical) at 1GHz
• 0.5mm thick uDFN package with 0.40mm lead
pitch:
• 4-channel = 8-lead uDFN
• 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
• Lead-free packaging
Applications
• LCD and camera data lines in mobile handsets
• Wireless handsets
• LCD and camera modules
Product Description
California Micro Devices’ 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.
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 CM1690 is ideal for EMI filter-
ing 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 pro-
file 8-, 12-, and 16-lead 0.40mm uDFN packages with
lead-free finishing.
