Xsight Labs, a fabless semiconductor start-up based in Israel, announced sampling of a 25.6T 32 x 800G data center switch and a 12.8T 32 x 400G data center switch based on 100G PAM4 SerDes.
The New X1 Family
According to the announcement, Xsight Labs’ X1 is the industry’s lowest power 25.6Tbps and 12.8Tbps fully programmable data center switch that have a new architecture to achieve new levels of power and silicon efficiencies. X1 switch chip is fabricated in 7nm silicon.
Erez Shaizaf, Xsight Labs’ Co-Founder and Switch General Manager said,
“Xsight Labs is the first in the world to sample a monolithic 7nm switch silicon that is on the frontier of the 100G SerDes ecosystem. It is a true testament to the caliber of engineering talent that we have been able to assemble and we, as a team, are extremely proud of our execution.”
Some highlights:
- The X1 chip operates at less than 300W for 25.6T and under 200W for 12.8T (for typical data center use cases)
- Built with256 x 100G LR PAM4 SerDes, X1 enables retimer-less design, supporting in-rack DAC connectivity for the 100G ecosystem.
- X1 supports the new 800G optics ecosystem, delivering a 2x improvement in port density vs. 400G optics.
- X1 leverages a fully shared buffer architecture with wire speed in-cast performance for worst-case microburst absorption.
- X1 supports an extensive suite of programmable Dataplane Telemetry that enables visibility into the
