The Platform

One Architecture.
Every Layer of the AI Data Center.

Linkedchip's four-stage platform covers signal integrity at the chip-to-chip level through data center-scale network switching. Each product is built on the same unified SerDes and protocol technology core.

This coherent architecture creates compounding performance advantages — our products interoperate natively, reducing latency and power across the complete interconnect stack.
