Microchip OS81118AF

Microchip Technology is providing support for smart antenna module connectivity to in-vehicle MOST150 advanced driver assistance system (ADAS) and infotainment networks through its OS81118AF Intelligent Network Interface Controller (INIC) with integrated coax transceiver. News comes as MOST Cooperation releases its MOST150 Technology Coaxial Physical Layer Specification. The low-cost coaxial cabling delivers in-car connectivity and power to these systems, simplifying design and installation as well as lowering costs.

The OS81118AF allows designers to create in-car cellular and Wi-Fi connectivity applications on the MOST150 network by connecting to a smart antenna module via a coaxial cable. This simple solution reflects today's market demands for wirelessly connected applications within the automotive environment, such as Internet access, email, social networking and location/GPS-based services.

The MOST150 technology was first deployed in the 2012 car models, and the first vehicles with the MOST150 Technology Coaxial Physical Layer are planned for model-year 2017. To date, more than 150 million MOST devices have been installed in over 180 car models since 2001. This cost-effective coaxial implementation of smart antenna modules allows for broad market adoption, and is expected to further expand the use of MOST technology in vehicles.


"We are excited that the MOST Cooperation released its MOST150 Technology Coaxial Specification," said Dan Termer, vice president of Microchip's Automotive Information Systems Division. "By employing the MOST150 Technology Coaxial Physical Layer, we are able to offer a technically superior solution with a robust physical layer and proven electromagnetic behaviour that allows cost-effective implementations of smart-antenna modules inside.

Microchip's OS81118AF cPhy INIC is available today for sampling, in a 72-pin QFN package.
