Samtec ExaMAX® High-Speed Backplane System

ExaMAX® high-speed backplane interconnects deliver 56 Gbps electrical performance.


FAMILY OVERVIEW

ExaMAX® Video

The ExaMAX® contact system achieves two reliable points of contact at all times and minimizes residual stub for improved signal integrity performance, while providing low mating force and excellent contact normal force. Signal wafers incorporate a one-piece, embossed ground structure which improves crosstalk performance.

Traditional backplane and direct-mate orthogonal available with backplane cable and coplanar versions in development.

FEATURES

A key component of any high-speed signal path is the interconnect.  Design engineers must identify the right connector (or connectors) and the best performance for the application. At 56 Gbps PAM4 data rates (and higher), connector selection becomes more challenging. Interconnect...
It’s been over a year since we last updated the Samtec homepage. As you may have already noticed, we recently took some time to refresh it. You can see a comparison below of the old homepage (top), vs the new homepage (bottom). The new update puts more attention on our high speed...
If you manufacture overseas and ship into the U.S.A, you may have a longer waiting time in Customs than you would prefer.  Some of this waiting time could be eliminated by becoming part of the Customs Trade Partnership Against Terrorism (C-TPAT), one layer of the U.S. Customs and...
Just about everybody wishes they had more time to pursue a hobby or a side project.  Some aspire to be painters or furniture makers.  Others like to rebuild cars.  Even others enjoy electronics in any form. The Maker Movement attracts and caters to tinkerers, hobbyists, students ...
Demand For High Data Rate As the need for bandwidth continues to increase, so does the need for higher data rates within a system. What was once one to three Gbps, then moved to 4 to 8 Gbps, and now we are approaching 28 Gbps and looking forward to 56 G. This trend was recently [...
