>Si-Fly 112 Gbps PAM4, Low-Profile High-Density Cable System

Si-Fly 112 Gbps PAM4, Low-Profile High-Density Cable System

Si-Fly uses direct connect technology to elude the BGA and route signals directly from the silicon package through a long-reach cable.


FAMILY OVERVIEW

Samtec - Direct Connect to IC Package

The ultra-high density design and on-package direct connect technology of Samtec’s Si-Fly cable system enables speeds of 25.6 TB aggregate, with a path to 51.2 TB. The signal channel eludes the BGA, routing directly from the IC package through a long-reach cable offering 5x the reach of traditional PCB topologies.
