Samtec ExaMAX® High-Speed Backplane System
Samtec ExaMAX® High-Speed Backplane System offers design flexibility to fit a variety of applications, including Flyover® cables supporting 112Gbps PAM4 and board-to-board connectors supporting 56Gbps PAM4. ExaMAX Backplane Systems are suitably designed for various industries, including 5G networking, medical, automotive, instrumentation, military/aerospace, and AI/machine learning.
56Gbps PAM4 Interconnects
The Samtec ExaMAX contact system achieves two reliable points of contact at all times and minimizes residual stub for improved signal integrity performance, while additionally providing low mating force and excellent contact normal force. Improved crosstalk is achieved due to the signal wafers incorporating a one-piece, embossed ground structure.
112Gbps PAM4 Cable Assemblies
ExaMAX backplane cable assemblies improve routability and signal integrity using Flyover technology, which routes the signal above a lossy PCB using co-extruded, ultra-low skew Twinax for improved reach and bandwidth. The direct solder-attach-to-contacts design optimizes the signal path, further enhancing performance.
