DESCRIPTION
Proliferation of digital portable LX7206 is an integrated low pass
electronic equipment has created a filter with ESD protection that filters
noisy environment in which all out the undesired frequencies as well as
devices become susceptible to protecting the port against both positive
Electromagnetic Interference (EMI). and negative ESD voltages. The device
Interference form cell phone is a 3x2 array flip chip and measures
frequencies of 800-900 MHz and 1.5 x 1.0 x 0.65 mm. The small size
1.9GHz as well as the growing and profile of this device is ideally
wireless LAN frequencies of 2.4- suited for portable applications. The
6GHz can couple into the audio port absence of leadframe and bondwires
of a handheld device and adversely minimizes inductance and optimizes the
affect its performance. FCC Part 15 high frequency filter performance.
sets maximum allowable emission and LX7206 exceeds the requirements of
immunity levels for all digital devices. IEC61000-4-2 (15KV air discharge and
8KV contact discharge).
