Inphi 16nm Polaris PAM4 Platform Named Winner in 2018 Lightwave Innovation Reviews Program

Solution Wins Lightwave Disruptive Technology for Data Center Interconnect Platforms

SANTA CLARA, Calif., March 22, 2018 – Inphi Corporation (NYSE: IPHI), a leader in high-speed data movement interconnects, today announced that its Polaris™ 16nm CMOS PAM4 Platform was recognized as a winner in the 2018 Lightwave Innovation Reviews program in the Data Center Interconnect Platforms category. Inphi was awarded during a reception celebrating finalists and winners on Wednesday, March 14, 2018 during the Optical Fiber Conference (OFC).

Lightwave judges noted, “This product family is targeting a very critical market segment and is industry leading in its capabilities. A full solution set targeting a range of implementations.”

Presented annually by Lightwave, the Lightwave Innovation Reviews program distinguishes top products and solutions available within the optical networking industry as determined by a stellar panel of third-party judges. Judges include industry executives and analysts from a wide variety of service providers, technology developers, industry analysts, and journalists.

“On behalf of the Lightwave Innovation Reviews, I would like to congratulate the outstanding winners,” said Lightwave Group Publisher Christine Shaw. “The 2018 program was competitive, and the top scoring companies exemplify innovation in the optical networking industry.”

“This prestigious recognition by pioneers in the optical industry further validates Inphi’s market leading innovation,” said Siddharth Sheth, SVP, Networking Interconnects at Inphi. “This endorsement substantiates our execution and production prowess towards setting an industry leading performance benchmark. Our Polaris™ 16nm CMOS PAM4 Platform delivers the performance, flexibility and scalability at the inflection point of hyperscale cloud networks that need 200G and 400G capability today.”

Polaris 16nm CMOS PAM4 platform Details:
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. The platform also supports a family of discrete EML and VCSEL drivers and linear TIAs. The Polaris platform expansion provides customers with a critical integration feature that significantly reduces cost and slashes power.

Polaris 16nm PAM4 DSP PHY Product Family:
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. The product family can support both Retiming and Gearbox functionality with options supporting standard driver or integrated driver functionality. Target products specifically designed for the following optics modules include:
• Polaris-400G – 8x56Gbps PAM4 <-> 16x28Gbps NRZ gearbox for CFP8
• Polaris-400G (NG) – 8x56Gbps <-> 8x56Gbps PAM4 retiming for OSFP / QSFP-DD
• Polaris-200G – 4x56Gbps <-> 4x56Gbps PAM4 retiming for QSFP56
• Polaris-100G – 2x56Gbps <-> 2x56Gbps PAM4 retiming for QSFP28
• Polaris-50G – 1x56Gbps <-> 1x56Gbps PAM4 retiming for SFP56 / SFP-DD

Polaris Linear Drivers:
The Inphi IN2831SZ (single channel) and the IN2834SZ (quad channel) are 28GBaud low power EML linear drivers for PAM4 optical modules. The IN2834SZ features excellent linearity, high bandwidth, adjustable gain to optimize the PAM4 system performances and two high frequency bias T integrated inside the package, one for driver to reduce the power consumption, the other one for EML bias voltage. A single channel die version, IN2830SZ is also available.

The Inphi IN2814DV is a 28GBaud low power quad VCSEL linear driver for PAM4 optical modules or Active Optical Cables (AOCs). The IN2814DV package is optimized for routing with a channel pitch aligned to the VCSEL optics driving over Multi-Mode Fiber (MMF).

Polaris Linear TIA’s:
The Inphi IN2864LP is a 28GBaud low power quad linear TIA for PAM4 optical modules optimized for shorter (<2km) client interfaces. The compatible IN2864TA TIA is optimized for longer reach (10km) interfaces. Both TIA’s feature a wide dynamic range to meet the different performance and link requirements for optical applications and excellent signal integrity necessary for PAM4 modulation schemes.

The Inphi IN2865TA is a 28GBaud low power quad VCSEL linear TIA for PAM4 optical modules or AOCs. The IN2865TA is optimized for direct routing with a channel pitch aligned to the MMF optics.
