CM1457
Description
The CM1457 is an inductor-based (L-C) EMI filter array with ESD protection, which integrates four, six, or eight filters in a CSP form factor with 0.40 mm pitch. Each EMI filter channel of the CM1457 is implemented with the ponent value of 6 p F
- 35 n H
- 4.7 p F
- 35 n H
- 1.8 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 ±15 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...
