1. Description

The LT84102M is a high performance Analog switch with wide voltage range capability. It supports DisplayPort 1.2/1.4, HDMI 1.4/2.0/2.1, Bi-directional USB3.2 Gen2 switching differential signal, and emerging and proprietary standards.
The LT84102M can pass high-speed signals to 1.38V peak to peak differential, with a common-mode voltage from 2V to VCC or 0V for TMDS signal. The wide voltage range allows DC-coupled or AC-coupled multi-standard operation.
In addition to two high-speed ports, the LT84102M also switches the DDC and HPD signals or AUX and HPD signals using the DDC/AUX and HPD channel mux/demux.
