MAX14982ETO+

Signal Buffers, Repeaters, Splitters Overview

The MAX14982ETO+ is a single-lane, ruggedized 5GT/s PCIe multiplexer and redriver with equalization capabilities. It integrates MUX and redriver functionalities into an all-in-one solution designed to switch between multiple hosts or sinks while overcoming circuit-board losses. The device operates from a single +3.3V supply and features bidirectional redrivers with independent programmable equalization, output preemphasis, and boost. It utilizes advanced power-saving techniques, entering standby mode when no drive is connected. The component is specified over the -40°C to +85°C industrial operating temperature range and is housed in a space-saving 42-pin TQFN package measuring 3.5mm x 9mm.
