Inphi has begun sampling its Porrima Gen3 Single-Lambda PAM4 platform based on 7nm technology and optimized for hyperscale data center networks. The new design offers an expanded feature set and enhanced direct drive capability, further expanding the breadth of lasers that can be used with the integrated laser driver. The new platform is also designed to reduce total module power consumption to less than 8W for 400Gbps DR4/FR4 mode in the QSFP-DD form factor.
“Porrima Gen3 is another prime example of our ongoing dedication to this market, by increasing investments to exceed customer needs and stay ahead of the competition,” said Eric Hayes, SVP, Networking Interconnect, Inphi. “Not only are we delivering better performance and lower power with this third-generation PAM4 solution, but we are also making it easy for customers to make a smooth transition. This will accelerate adoption of this total solution and maintain our market leadership position.”
Porrima Gen3 Key attributes and Benefits:
- Compatible API and software suite with Porrima Gen1 and Gen2 ensure smooth transition in deployment
