MOST150 Includes Coaxial Cable

MOST® Cooperation Releases MOST150 Electrical Physical Layer Specification
MOST150 Includes Coaxial Cable

The MOST Cooperation – the standardization organization for the leading automotive multimedia network Media Oriented Systems Transport (MOST) – has released the MOST150 Electrical Physical Layer Sub-Specification Rev. 1.0 based on coaxial cable. „This MOST150 coax physical standard complements the existing MOST150 optical physical layer in the infotainment domain, especially for OEMs who have stringent preferences in the electrical physical layer,“ stated Dr. Wolfgang Bott, Technical Coordinator of the MOST Cooperation. „In addition, this new standard opens the way into other vehicle domains i.e. it fits into the driver assistance domain, as this physical layer is able to provide bi-directional communication and power supply on the same cable.“ This specification was derived in a straight forward process from the MOST Physical Layer Basic Specification. Its principal structure is similar to the existing MOST150 optical physical layer specification. Both physical layers are interoperable: MOST150 supports various physical layers and enables various topology options.

Future-proof and Cost-efficient Network

Additionally, the well known advantages of the MOST150 optical physical layer are kept. MOST150 is a multi-channel network (control data, synchronous and packet channel) which allows the parallel usage of all these services through one network. It provides an isochronous channel for video data transmission, among others. It also enables IP data communication, providing the automotive-ready Ethernet channel according to IEEE 802.3. with freely configurable bandwidth from 0 to nearly 150 Mbit/s. MOST150 supports the safety layer concept to enable fail-safe application up to SIL level 3 according to IEC 61508 and ASIL C according to ISO 26262. Meeting these requirements, and due to its inherent synchronicity, the MOST standard provides an effective and cost-efficient network solution that is resilient and future-proof.

About MOST Technology
MOST (Media Oriented Systems Transport) is a multimedia networking technology optimized for use in cars and other applications. It enables the transport of high Quality of Service audio and video together with packet data and real-time control over a single transmission medium. MOST can use plastic optical fibers (POF), COAX based electrical physical layer, and shielded and unshielded twisted pair (STP/UTP) copper wires, that meet automotive environmental requirements. Today MOST is used in over 105 car models as the communication backbone for their information and entertainment equipment.

About MOST Cooperation
The MOST Cooperation is the organization through which MOST Technology is standardized and refined so that it continues to stay abreast of the latest industry requirements. Today it consists of 16 international carmakers and more than 60 key component suppliers. They have joined together to work with the MOST Technology and to contribute to its innovation. The MOST Cooperation is prepared to embrace efforts to further develop and standardize the technology for other industries and to establish the corresponding work structures. The MOST Cooperation was founded in 1998 to standardize MOST Technology as a global standard for multimedia networking. Audi, BMW, Daimler, HARMAN and SMSC are its core partners and constitute its Steering Committee. For more information see http://www.mostcooperation.com.
