All-In-One Ruggedized 5GT/s 2:1/1:2 PCIe Mux and Redriver with Equalization

The MAX14982 integrates MUX and redriver functionalities, offering an all-in-one solution capable of switching between multiple hosts or sinks and overcoming circuit-board losses. The solution is ideal for switching and redriving high-speed PCIe® 5.0GT/s (Gigatransfers per second) signals and operates from a single +3.3V supply.

The IC features bidirectional redrivers with built-in independent programmable equalization, output preemphasis, and boost that overcome transmission line noise while preserving signal integrity at the receiver.

The MAX14982 utilizes advanced power-saving techniques where power consumption is reduced by entering standby mode when no drive is connected. The device also features flow-through pin outs to simplify routing and increase layout flexibility.

The MAX14982 is available in a space-saving, 42-pin 3.5mm x 9mm, TQFN package optimal reducing layout complexity as compared to stand-alone mux and redriver solutions. The MAX14982 is specified over the -40°C to +85°C industrial operating temperature range. Applications
