MAX14982
All-In-One Ruggedized 5GT/s 2:1/1:2 PCIe Mux
and Redriver with Equalization
General Description
The MAX14982 integrates MUX and redriver functional-
ities, 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 inde-
pendent programmable equalization, output preemphasis,
and boost that overcome transmission line noise while
preserving signal integrity at the receiver.
The MAX14982 utilizes advanced power-saving tech-
niques 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.
