Polaris™ is the industry’s first 16nm CMOS PAM4 platform solution for hyperscale data center, service provider and enterprise networks. The foundation of Polaris is a highly configurable DSP Engine that is based on three generations of proven silicon and is designed to achieve performance levels for both multi-mode and single mode optical interconnects covering up to 10km, while keeping an extremely low power profile of optical module applications. The Polaris platform includes Inphi’s marketing-leading linear TIA and Driver.

Key Features

• DSP Engine with a unique mixed-mode DSP architecture for high performance, low power applications needing adaptability and configurability.
• Numerous self-test and loopback modes that allow diagnostic monitoring of channel and system parameters.
• Eye-scan, samplers and monitors on all receiver interfaces for link margin and stress testing along with GUI and API routines for data and error analytics.
