IC combines filtering and ESD protection

摘要

The ECMF02 and ECMF04 are silicon-based ICs that combine the common-mode filtering and ESD protection needed by high-speed data lines. The ICs target high-speed data circuits commonly used in smart- phones, tablets, and mobile comput- ers, as well as for wired connections such as USB2.0 and HDMI. The ECMF02 is a single-channel device, and the ECMF04 is a dual data-channel device. Both devices have 6-GHz differential bandwidth that complies with HDMI, MIPI D- PHY, and USB2.0 com- mon-mode attenuation requirements, with -34 dB at 900 MHz, and -20- dB between 800 MHz and 2.2 GHz.
