Microsemi . C OM 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 2.46GHz can couple into the audio port of a handheld device and adversely affect its performance. FCC Part 15 sets maximum allowable emission and immunity levels for all digital devices. LX7206 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 performan...
