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. • • • • • • • Four, six and eight channels of EMI filtering with integrated ESD protection Pi-style EMI filters in a capacitor-inductorcapacitor (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 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. ©2010 SCILLC. All rights reserved.
