The Inphi IN2831SZ (single channel) and the IN2834SZ (quad channel) are 28GBaud low power EML linear drivers for PAM4 optical modules. Polaris-50G – 1x56Gbps 1x56Gbps PAM4 retiming for SFP56 / SFP-DD.Polaris-100G – 2x56Gbps 2x56Gbps PAM4 retiming for QSFP28.Polaris-200G – 4x56Gbps 4x56Gbps PAM4 retiming for QSFP56.Polaris-400G (NG) – 8x56Gbps 8x56Gbps PAM4 retiming for OSFP / QSFP-DD.Polaris-400G – 8x56Gbps PAM4 16x28Gbps NRZ gearbox for CFP8.Target products specifically designed for the following optics modules include: The product family can support both Retiming and Gearbox functionality with options supporting standard driver or integrated driver functionality. Inphi’s 16nm PAM4 DSP PHY ICs provide a full bi-directional interface with host ASICs that have 28GBaud PAM4 and/or NRZ electrical interfaces while bridging to 28GBaud PAM4 optics. Polaris 16nm PAM4 DSP PHY Product Family: “We need energy-efficient DSP PHY ICs, drivers and TIAs such as the Inphi Polaris family to enable 50GbE, 200GbE, 400GbE and even next-gen 100GbE optics.” “The industry is on the cusp of an all-new ecosystem with PAM4 modulation and 56 Gb/s interfaces,” said Dale Murray, Principal Analyst for LightCounting Market Research. “We are very excited to have delivered the industry’s first production ready PAM4 DSP platform within 12 months of announcing the product and are prepared to ramp the platform along with the applications ranging from HPC, AI to 12.8T switch connectivity.” “Our Polaris PAM4 platform is seeing a lot of customer design win momentum supporting an inflection point of hyperscale cloud networks that need 200G and 400G capability today,” said Siddharth Sheth, SVP, Networking Interconnect, Inphi. The company will be showcasing the platform at multiple customer and partner booths at OFC 2018 in San Diego on March 13-15, 2018. The platform also supports a family of discrete EML and VCSEL drivers and linear TIAs. The Polaris platform is the industry’s first 16nm 28GBaud PAM4 DSP that includes integrated driver options for EML and VCSEL lasers to cover a broad range of optical interconnects from 50G to 400G. 13, 2018 – OFC 2018 – Inphi Corporation (NYSE: IPHI), a leader in high-speed data movement interconnects, today announced the production availability of the Polaris™ 16nm CMOS PAM4 platform. Industry’s First 28GBaud PAM4 DSP with Integrated EML and VCSEL Drivers Now Available for Volume Production
