MT2814

Programmable Baseband SoC 

Overview

Metanoia’s MT2814 is a higher end version of the MT2812. MT2814 is based on an integrated programmable baseband processor architecture for 5G applications such as standalone Small Cells as well as Split ones with Radio Unit (RU), Distributed Unit (DU),  satellite and  proprietary wireless connectivity applications. This innovative, highly integrated, programmable design is ideal for new and evolving standards or for custom wireless use cases such as Military, Aerospace, fixed wireless access or proprietary mesh schemes.

The MT2814 may be used as a high-performance co-processor for Open Radio Access Network (O-RAN)  architectures where the vector engine complex can serve as a dedicated layer 1 accelerator. Metanoia 5G target markets for MT2814 include O-RAN products (DU and RU) and customer premises equipment (CPE) applications.

The MT2814 programming is supported by Codewarrior® tools and Metanoia reference application software and libraries.

Applications

The MT2814 SoC supports a scalable architecture which can help in building higher density applications by using multiple instances of the chip.

Target Market Segments
