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 is offered in a 72-pin QFN package and is expected to be available for volume production in January 2014. Early adopters can apply for samples today and sampling production is expected to start in Q3/2013.
