CM1406 4 Channel EMI Filter Array with ESD Protection Features Product Description • • California Micro Devices's CM1406 is an EMI filter array with ESD protection, which integrates 4 pi filters (C-R-C). The CM1406 has component values of 15pF200Ω-15pF. The parts include ESD protection 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 diodes connected to the filter ports are designed and characterized to safely dissipate ESD strikes of ±15kV contact discharge, twice the specification requirement of the IEC 61000-4-2, Level 4 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 channels of EMI filtering with ESD protection Greater than 30dB of attenuation from 800MHz to 3GHz ±15kV ESD protection (IEC 61000-4-2, contact discharge) ±30kV ESD protection (HBM) 8-lead TDFN package (2mm x 2mm), 0.5mm pitch Lead-free version available Applications • • • I/O port protection for mobile handsets, notebook computers, PDAs etc. EMI filtering for data ports in cell phones, PDAs or notebook computers. EMI filtering for LCD and chip-to-chip data lines This device is particularly well suited for portable electronics (e.g. mobile handsets, PDAs, notebook computers) because of its small package format and easy-touse pin assignments. In particular, the CM1406 is ideal for EMI filtering and protecting data lines from ESD in wireless handsets. The CM1406 is available in a space-saving, low-profile, 8-lead, 2mm x 2mm TDFN package. It is fabricated with California Micro Devices' Centurion™ process and available with optional lead-free finishing.
