CM1457
Praetorian lll) 4-, 6-,
8-Channel EMI Filter Array
with ESD Protection
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 (ESD). The ESD protection diodes connected
to the external filter ports are designed and characterized to safely
dissipate ESD strikes of ±15 kV, which is beyond the maximum
requirement of the IEC6100042 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 CM1457 is ideal for
EMI filtering and protecting data and control lines for the LCD display
and camera interface in mobile handsets.
The CM1457 incorporates OptiGuardt which results in improved
reliability at assembly. It is manufactured with a 0.40 mm pitch and
0.25 mm CSP solder ball to provide up to 28% board space savings vs.
competing CSP devices with 0.50 mm pitch and 0.30 mm CSP solder
ball.
