ExaMAX® I/O Shielded, High-Density Cable System

ExaMAX® I/O Shielded, High-Density Cable System

Fully shielded, EMI protected I/O cable system using proven ExaMAX® technology with two reliable points of contact for 64 Gbps PAM4 (32 Gbps NRZ) performance in a cable-to-panel configuration.


Family Overview

Samtec's ExaMAX® external cable and cage system features EMI shielding to help limit signal degradation and optimize performance, supporting 64 Gbps PAM4 (32 Gbps NRZ) applications. The high-density design features up to 72 staggered differential pairs on individual signal wafers, which increases isolation and significantly reduces crosstalk. For additional signaling, one sideband per column is included. Eye Speed® ultra low skew cable technology improves bandwidth and extends signal reach.

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

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
