The new coaxial transceiver broadens Microchip’s portfolio of MOST150 network solutions and offers customers an additional option to implement efficient infotainment networks. It also enables easy migration from optical to coaxial cabling while protecting the customer’s investment in MOST150 technology.

The new transceiver solution reflects current market demands for automotive infotainment systems that include a navigation unit, antenna module, amplifier, tuner, Blu-ray player, rear-seat entertainment, instrument cluster, head-unit display, camera and more. MOST networking technology provides the means to distribute these multimedia entertainment functions among the various control devices inside the car. With an integrated coaxial-cable receiver featuring an equalizing function, the OS82150 coaxial transceiver assures robust and reliable network connectivity by providing automatic adaptation to various cable types and continuous compensation for initial and long-term cable-loss effects. Designed for automotive-grade electromagnetic compatibility (EMC), the device also integrates functions to minimise electromagnetic emissions and handle automotive electromagnetic interference (EMI) levels, facilitating smooth installations of MOST150 networks into vehicles.

By seamlessly interfacing with available MOST150 Intelligent Network Interface Controllers (INICs) the OS82150 can be easily integrated into existing designs. Additionally, the signal and timing specifications of the OS82150 are compliant with the MOST Physical Layer Specification, ensuring interoperability.

Additional features include a low-power sleep mode with activity detection for wake-on-signal functionality to facilitate the power management of electronic control units (ECUs) in the vehicle. Support for dual-simplex transmission allows for a ring topology that enables expandability and scalability of the network. A single, 3.3 volt power supply further eases design-in, as only a single voltage level is needed.

To support development and speed time to market, the OS82150 is accompanied by K2L’s OS81110 cPhy Evaluation Board and K2L’s OptoLyzer MOCCA Bundles. The OS81110 cPhy Evaluation Board encapsulates an entire MOST150 network device. An integrated OS85650 I/O Companion Chip (IOC) provides I/O port expansion for additional application flexibility. The OptoLyzer MOCCA Bundle combines the capabilities of the popular OptoLyzer Suite graphical user interface with the advantages of the OptoLyzer MOCCA multi-bus hardware interface.
