Syrma™

High performance IP solution enabling next-generation networking switches, routers, adapters and 5G.

Syrma™

High performance IP solution enabling next-generation networking switches, routers, adapters and 5G.
Inphi’s Syrma™ is the first generation, high performance 7nm 56Gbps SerDes IP solution. It is designed to ensure high performance across demanding environments and provide a highly efficient, high-performance SerDes driving chip to chip and optical connectivity. Deployed in both Inphi products and customers’ ASICs, Capella delivers longer reach, lower power, and cost efficiency to today’s networking switch, adapter and AI applications.
