EMI9404
Description
The EMI9404 is an inductor- based (L- C) EMI filter array with ESD protection, which integrates four filters in a UDFN package with 0.40 mm pitch. Each EMI filter channel of the EMI9404 is implemented with the ponent value of 1.8 p F- 35 n H- 4.7 p F- 35 n H- 6 p F. The cut- off frequency at
- 3 d B attenuation is 300 MHz and can be used in applications where the data rates are as high as 160 Mbps, while providing greater than
- 35 d B 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 k V, 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...
