CM1454
Data Port EMI Filter Array
with ESD Protection
Description
The CM1454 is an EMI filter array with ESD protection in a CSP
form factor for the data port of a mobile handset. The CM1454 ? 08 is
configured in an 8 channel format and combines both
resistor ? capacitor (R ? C) and inductor ? capacitor (L ? C) filters in the
chip. There are five C ? R ? C filters with component values of 30 pF ?
100 W ? 30 pF which are used for the microphone and data ports.
There are also three C ? L ? C filters with values of 80 pF ? 3 nH ? 80 pF
which are designed for the stereo speaker port.
The CM1454’s C ? RC filters have a cut ? off frequency of 60 MHz
and an attenuation of better than 35 dB over the 800 MHz to 2.7 GHz
frequency range. The C ? L ? C filters have a cut ? off frequency of
21 MHz with an attenuation of 40 dB at 1 GHz. The parts integrate
ESD protection diodes on every pin that provide a very high level of
protection for sensitive electronic components against possible
electrostatic discharge (ESD). The ESD protection diodes connected
to the filter ports are designed and characterized to safely dissipate
ESD strikes of ± 15 kV, which is beyond the Level 4 requirement of the
IEC61000 ? 4 ? 2 international standard. In accordance with
MIL ? STD ? 883 (Method 3015) specification for Human Body Model
(HBM) ESD, the pins are also protected for contact discharges at
greater than ± 30 kV.
The CM1454 incorporates OptiGuard t which results in improved
reliability at assembly. The CM1454 is available in a space saving, low
