1394 CU Copper Automotive Standard

The 1394 Trade Association recently announced the new 1394 Automotive specification for copper cabling media, designed to optimize the use of the 1394 (FireWire) standard in entertainment, environmental control, camera, and other in-vehicle applications. The new specification extends the original IDB-1394 Automotive Specification to include operation over cost-effective automotive-grade, high-performance copper cabling media. All of the features and mechanisms are provided for high-speed extensions with forward and backward compatibility enabling single-hop distances of up to eight meters through five or more in-line connectors. The specification covers the use of coaxial cable, shielded twisted pair, and shielded twisted quad media for critical non-safety vehicle functions such as multimedia and telematics applications at data rates of 400 Megabit/second or 800 Megabits/second.

The new document includes details on ICs that are compatible and supplemental to the original IDB-1394 Plastic Optical Fiber (POF) products used in hybrid optical and electrical networks. It also applies to ICs for use in embedded vehicle systems networks and to attach clusters of embedded 1394 devices. The new specification also incorporates comprehensive improvements in power management specific to the automotive market.

The original IDB-1394 Automotive standard is an international data networking standard for transmitting video, audio, and other multimedia data over an in-vehicle network. It enables entertainment systems that can play DVDs, show digital TV programming, and provide access to the vehicle navigation system.

Known commercially as FireWire and i.LINK, 1394 has been designed into a wide range of consumer, computer, industrial and other products since its inception, and is now emerging as a vital standard for automotive systems.
