Inphi Introduces Spica – World’s First 800Gbps PAM4 Electro-Optics Platform for Megascale Data Centers and AI Networks

800G 7nm PAM4 DSP Solution Supporting 100G per Lane with Linear TIA and Drivers Breaks New Technology Frontiers for Optical Transceiver Module Applications

SANTA CLARA, Calif., March 09, 2020 (GLOBE NEWSWIRE) -- Inphi Corporation (NYSE: IPHI), a leader in high-speed data movement interconnects, today announced that the company is sampling its new Spica™ 800G 7nm PAM4 DSP, the world’s first 800Gbps or 8x100Gbps PAM4 DSP to enable 800G optical transceiver modules in QSFP-DD800 or OSFP form factors. The highly integrated Spica 800G platform includes Inphi’s high-performance, low power PAM4 DSPs alongside its companion market leading low power linear driver and TIAs.

Until today, PAM4 optical modules could only support 400G, which limits the density available in a single system. Yet the industry has a relentless thirst for more bandwidth and the desire for lower power and a smaller footprint. These needs are driving the demand for high density switching systems. In order to accomplish this, a new generation of PAM4 DSPs are required to double the bandwidth of each optical module. Each of these new modules will need to support up to 800Gbps of bandwidth with a 100Gbps per lane electrical interface. In turn, a 1 RU 32 port switch will then be able to support 25.6Tb/s.

In addition, the performance of GPUs, network accelerators and artificial intelligence (AI) processors continue to skyrocket. This leap in performance demands higher speed of electrical and optical interfaces at 100Gbps per lane, to achieve the necessary bandwidth for connectivity to transfer the vast amount of data between chips and between AI clusters.

Leveraging seven generations of industry leading PAM4 DSP development, the Spica 800Gbps PAM4 DSP platform provides the total solution of electronics for module design. The new low power, PAM4 DSP with integrated 56GBaud driver, enables either 2x400Gbps or 8x100Gbps optical modules with 100Gbps per lane electrical interfaces. Customers are now able to develop 800Gbps / 8x100Gbps optical interconnects in a compact form factor for applications with single mode fibers or multimode fibers. Together with Inphi’s proven 112Gbps Capella™ SerDes IP for next generation AI processors and switches, the new Spica PAM4 DSP enables the critical transition of optical connectivity inside and between AI clusters.

“The delivery of high-performance, high density and low power PAM4 800G optical modules is critical to enable the next generation of networking and AI systems,” said Osa Mok, Chief Marketing Officer of InnoLight Technology. “Inphi’s ongoing commitment to innovation and market leadership will help us to stay one step ahead of the competition and make 800G optical modules a reality.”

“Inphi is once again breaking a technology barrier to lead our industry, building on our strong track record of successfully executing consecutive leaps over technical hurdles because of our unique approach and our commitment to innovation,” said Eric Hayes, SVP, Networking Interconnect, Inphi. “As a market leader and the most reliable electronics partner that customers can depend on, we are first to bring new products to customers – a hallmark Inphi has come to be known for, and with best-in-class performance.”
