USB 2.0 interface, coax physical layer on MOST150 network chip
The OS81118 enables automotive engineers to connect up-to-date multi-core consumer Systems-on-a-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).
The OS81118 supports the trend in the infotainment market to use high-end SoCs, developed for consumer and mobile devices, within automotive applications. However, those SoCs have no automotive-specific interfaces, such as CAN, LIN, MediaLB or MOST. The high-speed USB port on the OS81118 makes it easy to connect SoCs to any MOST150 automotive network, with the added flexibility provided by the coax transceiver.
To enable development and speed time to market, Microchip is also announcing the Physical+ Interface Board OS81118. This board encapsulates the entire physical hardware interface of a MOST network. The Physical+ Interface Board OS81118 comes with a USB 2.0 interface supporting optical and coaxial physical layers, and is expected to be available in Q3/2013.
The OS81118 occupies a 72-pin QFN package and will be available for volume production in January 2014.
