Integrated EMI Filter & ESD Protection For
Earpiece Speaker Ports
TM
DESCRIPTION
Proliferation
of
digital
portable
electronic equipment has created a
noisy
environment
in
which
all
devices
become
susceptible
to
Electromagnetic Interference (EMI).
Interference
form
cell
phone
frequencies of
800-900 MHz and
1.9GHz as well as the growing
wireless LAN frequencies of 2.4-
6GHz can couple into the speaker port
of a handheld device and adversely
affect its performance. FCC Part 15
sets maximum allowable emission and
immunity levels for all digital devices.
LX7205 is an integrated low pass
filter with ESD protection that filters
out the undesired frequencies as well as
protecting the port against both positive
and negative ESD voltages. The device
is a 3x2 array flip chip and measures
1.5 x 1.0 x 0.65 mm. The small size
and profile of this device is ideally
suited for portable applications.
The
absence of leadframe and bondwires
minimizes inductance and optimizes the
high
frequency
filter
performance.
LX7205 exceeds the requirements of
IEC61000-4-2 (15KV air discharge and
8KV contact discharge).
