| LCD EMI Filter Array with ESD Protection CM1420-22 Features * * * * * * * Functionally and pin compatible with CSPEMI606 (CM1420) and CSPEMI608 (CM1422) devices OptiGuardTM coated for improved reliability at assembly Six and eight channels of EMI filtering +15kV ESD protection on each channel (IEC 61000-4-2 Level 4, contact discharge) +30kV ESD protection on each channel (HBM) Better than 30dB of attenuation at 1GHz to 3GHz Chip Scale Package features extremely low lead inductance for optimum filter and ESD performance 15-bump, 2.960mm x 1.330mm footprint Chip Scale Package (CM1420) 20-bump, 4.000mm x 1.458mm footprint Chip Scale Package (CM1422) RoHS compliant (lead-free) finishing Product Description The CM1420 and CM1422 are EMI filter arrays with ESD protection, which integrate six and eight Pifilters (C-R-C), respectively. The CM1420/22 has component values of 15pF-100-15pF. These devices 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 safely dissipate ESD strikes of 15kV, well beyond the maximum requirement of the IEC 61000-4-2 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 portable electronics (e.g. wireless handsets, PDAs, notebook computers) because of its small package format and easy-to-use pin assignments. In particular, the CM1420/22 is ideal for EMI filtering and protecting data lines from ESD for the LCD display in clamshell handsets. The CM1420 and CM1422 incorporate OptiGuardTM coating which results in improved reliability at assembly. The CM1420 and CM1422 are available in space-saving, low-profile chip-scale packages with RoHS compliant lead-free finishing. * * * Applications * * * * * * LCD data lines in clamshell wireless handsets EMI filtering & ESD protection for high-speed I/O data ports Wireless handsets / cell phones Notebook computers PDAs / Handheld PCs EMI filtering for high-speed data lines (c)2010 SCILLC.
