4 Channel Headset EMI Filter With ESD Protection

The CM1410 is a quad low-pass Filter array integrating four pi-style Filters (C-R-C) that reduce EMI RFI emis- sions while at the same time providing ESD protection. This device is custom-designed to Interface with the headset port on a cellular telephone, and contains 3 different Filter values. Each high quality Filter provides more than 20dB attenuation in the 800-2700 MHz range. These pi-style Filters support bidirectional filter- ing, controlling EMI both to and from the Microphone and speaker elements. They also support bipolar sig- nals, enabling Audio signals to pass through without distortion. By California Micro Devices Corporation
