4-, 6-, 8-Channel EMI Filter Array with ESD Protection 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 component value of 6 pF − 35 nH – 4.
7 pF − 35 nH – 1.
8 pF.
The cut-off frequency at −3 dB 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 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 (...
