Microchip unveiled the OS81118, the first MOST150 Intelligent Network Interface Controller (INIC) with a USB 2.0 high-speed device port and an integrated coax transceiver.
MOST multimedia networking technology enables the interconnection of feature-rich infotainment systems in automobiles by providing the means to distribute multimedia entertainment functions among the various control devices inside the car. For example, CD or DVD changer, radio, GPS navigation, mobile telephone and digital media interfaces can supply signals to this efficient network. The signals are sent digitally and static-free to the amplifier and monitors.
With its USB 2.0 port, including USB PHY and High-Speed Inter-Chip interface (HSIC), the OS81118 allows designers to create in-car mobile and Wi-Fi connectivity applications on the MOST150 network by connecting a standard Wi-Fi/3G/LTE module via USB.
This simple solution reflects today’s market demands for consumer applications within the automotive environment, such as Internet access, e-mail, social networking and local services. Furthermore, the new chip enables automotive engineers to connect the most up-to-date multicore consumer systems-on-chip (SoCs) to in-vehicle MOST networks.
Besides the optical physical layer (oPHY) interface, the OS81118 integrates a coax transceiver, which opens a cost-reduction path on the MOST physical layer. Additionally, this coaxial physical layer (cPHY) could be used for Advanced Driver Assistance Systems (ADAS).
To further enable development and speed time to market, Microchip also announced the Physical+ Interface Board OS81118. This board encapsulates the entire physical hardware interface of a MOST network and comes with a USB 2.0 interface supporting optical and coaxial physical layers.
