1394 Trade Association Creates IEEE 1394 Baseband Over Coax Task Group to Develop Specification for Automotive, Home, Industrial Networking.DALLAS -- The 1394 Trade Association has established a new task group to develop an IEEE (Institute of Electrical and Electronics Engineers, New York, www.ieee.org) A membership organization that includes engineers, scientists and students in electronics and allied fields. 1394 baseband over coaxial cable PMD (Polarization Mode Dispersion) The type of dispersion that occurs in singlemode fiber due to a lack of perfect symmetry in the fiber and from external pressures on the cable. Light travels over singlemode fiber in two polarization states. specification for use across a wide range of automotive, residential, and industrial networking applications. The task group will work under the auspices of the 1394 Trade Association's Silicon Working Group, with support from the group's Automotive Working Group. It will be chaired by Les Baxter Les Baxter (March 14, 1922–January 15, 1996) was an American musician and composer. Baxter studied piano at the Detroit Conservatory before moving to Los Angeles for further studies at Pepperdine College. , a veteran member of the Trade Association who is the founder of Baxter Enterprises and chair of the IEEE P1394r committee, which is updating and revising the entire suite of IEEE 1394 standards. A prototype of this technology has been demonstrated by Eqcologic NV, a 1394 Trade Association member company. Baxter said the task group will create two documents -- a requirements document and the PMD specification, which will include power options as well as the electrical transmission specification. Proposed performance will be bi-directional at data rates of 800 Megabits/second over 18 meters of coax with up to five inline connectors. Development of the 1394 baseband over coax specification will complement the coax bridge and UTP UTP (uridine triphosphate): see uracil. (Unshielded Twisted Pair) See twisted pair. UTP - unshielded twisted pair PMD specifications already developed by the 1394 Trade Association. Baxter said, "The baseband coax PMD will be a simple, low-cost interface that will provide high throughput in harsh EMC (1) (EMC Corporation, Hopkinton, MA, www.emc.com) The leading supplier of storage products for midrange computers and mainframes. Founded in 1979 by Richard J. Egan and Roger Marino, EMC has developed advanced storage and retrieval technologies for the world's largest companies. environments while using economical coaxial cables and standard connectors. The baseband coax interface also will have the potential to support higher data rates and/or longer distances." The IEEE 1394 standard is the optimal method for delivering high quality audio and video, because the bandwidth required for A/V (1) (Audio/Video) Refers to equipment and applications that deal with sound and sight. The A/V world includes microphones, tape recorders, audio mixers, still and video cameras, film projectors, slide projectors, VCRs, CD and DVD players/recorders, amplifiers and streaming is guaranteed, and because 1394 uses a reference clock to maintain optimal A/V signal synchronization (1) See synchronous and synchronous transmission. (2) Ensuring that two sets of data are always the same. See data synchronization. (3) Keeping time-of-day clocks in two devices set to the same time. See NTP. . The 1394 Trade Association is a worldwide organization dedicated to the advancement and enhancement of the IEEE 1394 standard. For more information visit www.1394ta.org |
