CM1460 Praetorian™ L-C LCD and Camera EMI Filter Array with ESD Protection Features 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 channel 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 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 IEC61000-42 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-resistor-capacitor (C-R-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 20dB attenuation (typical) at 1 GHz TDFN package with 0.50mm lead pitch: • 4-ch. = 8-lead TDFN • 6-ch. = 12-lead TDFN • 8-ch. = 16-lead TDFN Tiny TDFN package size: • 8-lead: 2.00mm 2.00mm • 12-lead: 3.00mm x 1.35mm • 16-lead: 4.00mm x 1.60mm Increased robustness against vertical impacts during manufacturing process Lead-free version available Applications • • • • • • 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 CM1460 is ideal for EMI filtering and protecting data and control lines for the LCD display and camera interface in mobile handsets. LCD and Camera data lines in mobile handsets I/O port protection for mobile handsets, notebook computers, PDAs etc. EMI filtering for data ports in cell phones, PDAs or notebook computers. Wireless handsets Handheld PCs/PDAs LCD and camera modules 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.
