ExaMAX® High-Speed Backplane System

ExaMAX® High-Speed Backplane System

ExaMAX® high-density backplane systems offer design flexibility to fit a variety of applications, including Flyover® cable supporting 112 Gbps PAM4 and board-to-board supporting 64 Gbps PAM4 (32 Gbps NRZ).


Family Overview

ExaMAX® level2

112 Gbps PAM4 cable assemblies:
ExaMAX® backplane cable systems improve signal integrity and routability using Samtec Flyover® technology, which routes the signal above a lossy PCB using co-extruded, ultra-low skew twinax for improved bandwidth and reach. Direct solder attach to contacts optimizes the signal path, further enhancing performance. Supports 112 Gbps PAM4 applications and is PCIe® 6.0/CXL 3.1 capable.

64 Gbps PAM4 interconnects: 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. Supports 64 Gbps PAM4 (32 Gbps NRZ) applications and is PICe® 6.0/CXL 3.1 capable.

Ultra-Low Skew Cable Technology

Samtec's proprietary co-extruded Eye Speed® twinax cable technology eliminates the performance limitations and inconsistencies of individually extruded dielectric twinax cabling; improving signal integrity, bandwidth and reach for high-performance system architectures.

Ultra Low Skew Twinax
  • Ideal for 28-112+ Gbps applications
  • Tight coupling between signal conductors
  • Improved bandwidth and reach
  • Improved signal integrity and eye pattern opening
  • Low skew (< 3.5 ps/meter) over extended lengths

Contact System

  • Two reliable points of contact
    • Even when subjected to angled mating
  • Meets Telecordia GR-1217 CORE specification
  • 2.4 mm mating surface area (contact wipe)
  • Minimizes residual stub
  • Clear separation between contact points
  • Lowest mating force on the market
  • Excellent contact normal force

Wafer Design

  • Individual signal wafers
    • Staggered, differential pair design
    • 24-72 pairs
  • Ground Plane
    • One-piece, embossed ground structure
    • Increased isolation significantly reduces crosstalk
    • Ground signal placement engineered for 92Ω impedance
      • Addresses both 85 and 100Ω applications
    • Balanced differential pairs are arranged in columns with zero skew
Wafer Design

Stub-Free Mating

  • Fully protected terminals on both backplane and daughtercard connectors ensure stub-free mating
  • Hermaphroditic mating interface provides reliable mating, protects pins
Stub Free

Mechanical Specifications

  • Mating force: 0.36 N max per contact
  • Unmating force: 0.12 N min per contact
  • Current rating: 0.5 A per signal contact
    • 0 < 30 ᵒC temp rise above ambient
  • -55 ᵒC to +85 ᵒC operating temperature
  • Press-fit termination to PCB
  • Manufacturing friendly 0.36 mm PTH for signals and 0.50 mm for grounds
