CM1621-06DE

Overview

The CM1621-06DE is a six-channel RC filter integrated circuit designed for EMI suppression and electrostatic discharge (ESD) protection in high-speed data lines. It incorporates a Pi-style capacitor-resistor-capacitor network structure within each channel to attenuate electromagnetic interference across the frequency range of 800 MHz to 2.7 GHz, providing approximately 35 dB attenuation. The device features an integrated ESD protection mechanism rated at 15 kV contact discharge and 8 kV air gap discharge, ensuring robust defense against transient voltage events. Operating within a temperature range of -40°C to +85°C, it utilizes a compact UDFN package to minimize board space consumption while maintaining signal integrity for sensitive mobile and portable electronic applications.
