The EMI9408 is an inductor?based (L?C) EMI filter array withESD protection, which integrates eight filters in a uDFN package with0.40 mm pitch. Each EMI filter channel of the EMI9408 isimplemented with the component value of1.8 pF?35 nH–4.7 pF?35 nH–6 pF. The cut?off frequency at 3dBattenuation is 300MHz and can be used in applications where the datarates are as high as 160 Mbps, while providing greater than ?35 dBattenuation over the 800 MHz to 2.7 GHz frequency range. The partsinclude ESD diodes on every I/O pin and provide a high level ofprotection against electrostatic discharge (ESD). The ESD protectiondiodes connected to the external filter ports are designed andcharacterized to safely dissipate ESD strikes of ±14 kV, which isbeyond the maximum requirement of the IEC61000?4?2 internationalstandard.

This device is particularly well suited for wireless handsets, mobileLCD modules and PDAs because of its small package format andeasy?to?use pin assignments. In particular, the EMI9408 is ideal forEMI filtering and protecting data and control lines for the LCD displayand camera interface in mobile handsets.

The EMI9408 is housed in space saving, low profile, 0.40 mm pitchuDFN packages in a RoHS compliant, Pb?Free format.

• Greater than 35dB Attenuation at 1GHz
