| PRELIMINARY CM1426 LCD and Camera EMI Filter Array with ESD Protection Features * * * * * * * * * Four, six and eight channels of EMI filtering with integrated ESD protection 0.5mm pitch, 10-bump, 1.96mm x 1.33mm footprint Chip Scale Package (CM1426-04) 0.5mm pitch, 15-bump, 2.96mm x 1.33mm footprint Chip Scale Package (CM1426-06) 0.5mm pitch, 20-bump, 3.96mm x 1.33mm footprint Chip Scale Package (CM1426-08) Pi-style EMI filters in a capacitor-resistor-capacitor (C-R-C) network 8kV ESD protection on each channel (IEC 61000-4-2 Level 4, contact discharge) 15kV ESD protection on each channel (HBM) Greater than 20dB attenuation (typical) at 1 GHz Chip Scale Package features extremely low lead inductance for optimum filter and ESD performance OptiguardTM coated for improved reliability at assembly Lead-free version available Product Description The CM1426 is a family of pi-style EMI filter arrays with ESD protection, which integrates four, six and eight filters (C-R-C) in a Chip Scale Package with 0.50mm pad pitch. The CM1426 has component values of 8.5pF-100-8.5pF per channel. The CM1426 has a cut-off frequency of 230MHz and can be used in applications where the data rates are as high as 92Mbps. The parts include avalanche-type 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 safely dissipate ESD strikes of 8kV, well 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 15kV. These devices are particularly well-suited for portable electronics (e.g. wireless handsets, PDAs, notebook computers) because of their small package and easyto-use pin assignments. In particular, the CM1426 is ideal for EMI filtering and protecting data and control lines for the I/O data ports, LCD display and camera interface in mobile handsets. The CM1426 incorporates OptiguardTM which results in improved reliability at assembly. The CM1426 is available in a space-saving, low-profile Chip Scale Package with optional lead-free finishing. * * Applications * * * * * * 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.
