? semiconductor components industries, llc, 2011 march, 2011 ? rev. 3 1 publication order number: CM1421/d CM1421 4-channel lcd emi filter array and esd protection array product description the CM1421 is a multichannel array consisting of four low ? pass filters with integrated esd protection and four esd ? only protection channels designed to reduce emi/rfi emissions on lcd data lines in mobile handsets. the CM1421 has component values of 15 pf ? 100 ? 15 pf. 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 15 kv, exceeding 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 30 kv. this device is particularly well ? suited for portable electronics (e.g. wireless handsets, pdas, notebook computers) because of its small package and easy ? to ? use pin assignments. in particular, the CM1421 is ideal for emi filtering and protecting data lines from esd for the lcd display in clamshell handsets. the CM1421 incorporates optiguard coating which results in improved reliability. the CM1421 is available in space ? saving, low ? profile chip scale packages with rohs ? compliant lead ? free finishing. features ? functionally and pin ? compatible with cspemi607 device ? four channels of combined emi/rfi filtering + esd protection ? four additional channels of esd ? only protection ? better than 30 db attenuation (typical) at 1 ghz ? 15 kv esd protection on all channels (iec 61000 ? 4 ? 2 level 4, contact discharge) ? 30 kv esd protection on all channels (hbm) ? chip scale package features extremely low lead inductance for optimum filter and esd performance ? 15 ? bump, 2.960 mm x 1.330 mm footprint ? optiguard coated for improved reliability ? these devices are pb ? free and are rohs compliant applications ? lcd data lines in mobile handsets ? emi filtering and esd protection for both data and i/o ports ? mobile handsets ? handheld pcs / pdas ? notebook computers marking diagram device package shipping ? ordering information http://onsemi.com csp ? 15 (pb ? free) 3500/tape & reel CM1421 ? 03cp n213 = CM1421 ? 03cp m = date code = pb ? free package (note: microdot may be in either location) wlcsp15 cp suffix case 567bs n213 m ?for information on tape and reel specifications, including part orientation and tape sizes, please refer to our tape and reel packaging specification brochure, brd8011/d.
