Seoul, April 2, 2015 – Microchip Technology (Korea Representative: Byung-Don Han), a global leader in microcontroller, mixed-signal, analog, and Flash-IP solutions, announced the MOST150 technology coaxial physical layer specification, a new industry standard released by the MOST® Association, and stated that it supports the connection of smart antenna modules to in-vehicle MOST150 advanced driver assistance systems (ADAS) and infotainment networks through Microchip’s OS81118AF intelligent network interface controller (INIC) with an integrated coaxial transceiver.

The MOST150 coaxial physical layer is ideal for data traffic originating from smart-antenna telematics and AM/FM, DAB, SDARS, DVB-T, 3G/LTE, GPS, and Wi-Fi® signals. These signals require greater interconnection with in-vehicle networks for high-bandwidth control, audio, video, and Internet Protocol (IP) communication. Additionally, the new standard enables the simultaneous supply of communication signals and power to these in-vehicle systems using proven low-cost coaxial cabling, simplifying design and installation efforts, reducing costs, and decreasing vehicle weight, thereby making it easier to meet environmental regulatory requirements.

The OS81118AF enables developers to implement in-vehicle cellular/Wi-Fi® connectivity applications on MOST150 networks by connecting to a smart antenna module via coaxial cable. This simple solution reflects the latest requirements of the wireless connectivity application market within automotive environments, such as internet access, email, social networks, and location tracking/GPS-based services. MOST150 technology was first installed in 2012 automotive models, and the MOST150 technology coaxial physical layer is scheduled to be applied for the first time in 2017 models. Since 2001, more than 150 million MOST devices have been installed in over 180 automotive models. This cost-effective coaxial layer implementation of smart antenna modules is expected to be widely adopted in the market, further expanding the use of MOST technology in vehicles.

"It is very encouraging that the MOST150 technology coaxial standard has been announced by the MOST Association," said Dan Termer, Vice President of Microchip's Automotive Information Systems business unit. "We thank our customers and the MOST Association staff for their efforts in making this launch announcement possible. By utilizing the MOST150 technology coaxial physical layer, Microchip will enable the cost-effective implementation of in-vehicle smart antenna modules by providing excellent technical solutions featuring a robust physical layer and proven electromagnetic characteristics."
