Microchip has announced that MOST has released its MOST150 Technology Coaxial Physical Layer specification. This industry-standard specification enables Microchip to support smart antenna module connectivity to in-vehicle MOST150 ADAS and infotainment networks, via its OS81118AF Intelligent Network Interface Controller with integrated coax transceiver.
The MOST150 coaxial physical layer is suited for smart-antenna telematics and other data traffic from AM/FM, DAB, SDARS, DVB-T, 3G/LTE, GPS and WiFi signals that increasingly need to connect with in-vehicle networks for high-bandwidth control, audio, video and IP communication. Additionally, the ability to utilise the proven and low-cost coaxial cabling to simultaneously deliver communication signals and power to these in-vehicle systems simplifies design and installation efforts while lowering costs and reducing vehicle weight for easier compliance with environmental regulations.
The OS81118AF allows designers to create in-car cellular and WiFi 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, e-mail, 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 150m 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.
