EMI9408: L-C EMI Filter Array with ESD Protection

The EMI9408 is an inductor−based (L−C) EMI filter array with ESD protection, which integrates eight filters in a uDFN package with 0.40 mm pitch. Each EMI filter channel of the EMI9408 is implemented with the component value of 1.8 pF−35 nH–4.7 pF−35 nH–6 pF. The cut−off frequency at 3dB attenuation is 300MHz and can be used in applications where the data rates are as high as 160 Mbps, while providing greater than −35 dB attenuation over the 800 MHz to 2.7 GHz frequency range. The parts include ESD diodes on every I/O pin and provide a high level of protection against electrostatic discharge (ESD). The ESD protection diodes connected to the external filter ports are designed and characterized to safely dissipate ESD strikes of ±14 kV, which is beyond the maximum requirement of the IEC61000−4−2 international standard. This device is particularly well suited for wireless handsets, mobile LCD modules and PDAs because of its small package format and easy−to−use pin assignments. In particular, the EMI9408 is ideal for EMI filtering and protecting data and control lines for the LCD display and camera interface in mobile handsets. The EMI9408 is housed in space saving, low profile, 0.40 mm pitch uDFN packages in a RoHS compliant, Pb−Free format.
