Samtec 28Gbps+ Interconnect

Samtec 28Gbps interconnect portfolio

Samtec board

The Avnet and Samtec partnership delivers tomorrow’s complex electronic design solutions. We bring people and technology together through on-site, local and regional training events and leading-edge online development tools. We dedicate ourselves to making the product selection, evaluation and design process easier for our customers, answering a new generation of technical and business needs.

Increasing data rates, denser systems and shrinking product footprints challenge designers to meet their system high-speed interconnect needs. Samtec provides engineers the service, products, tools and resources to optimize the entire system signal chain from the backplane to the front panel.

ExaMAX® high-speed backplane connector system

ExaMAX® high speed backplane interconnects deliver 28 Gbps electrical performance while offering a migration path to 56 Gbps.

ExaMAX High-Speed Backplane Connector System


  • Enables 28 Gbps electrical performance on 2.00 mm column pitch
  • Exceeds OIF CEI-28G-LR specification for 28 Gbps standards
  • Individual signal wafers in a staggered, differential pair design:
    • 72-pair design: 6-pair x 12 column
    • 40-pair design: 4-pair x 10 column
  • Wafer incorporates a one-piece embossed ground structure:
    • Increased isolation significantly reduces crosstalk
  • Ground placement engineered for:
    • 92Ω option addresses both 85Ω and 100Ω applications
  • Balanced differential pairs are arranged in columns with zero skew
  • Press-fit tails provide a reliable electrical connection between the connector and the board
  • Blind mate capable with built-in macro and micro guidance modules that allow for self-capture, self-alignment and mating without damage.
  • High power modules deliver bulk current to mating power components at 80 A per module.
