1394 Trade Association Announces 3.2 Gigabit per Second Speed for FireWire
New S3200 Specification Delivers Higher Speed Than Competing Technologies - and Much Sooner - With No Changes to Connectors or Cables
DALLAS -- December 17, 2007 -- The 1394 Trade Association today announced a new specification to quadruple the speed of FireWire to reach 3.2 gigabits per second.
The new electrical specification, known as S3200, builds upon the IEEE 1394b standard, preserving all the advantages of FireWire while offering a major and unprecedented boost in performance. The new speed uses the cables and connectors already deployed for FireWire 800 products, making the transition forward easy and convenient for 1394 product vendors and their customers. Because the 1394 arbitration, data, and service protocols were not modified for S3200, silicon and software vendors can deploy the faster speed FireWire quickly and with confidence that it will deliver its full potential performance. The S3200 specification is expected to be ratified by early February.
FireWire 800 products deployed since 2003 have proven that IEEE 1394b delivers outstanding performance. Operating without polling, without idle times, and without continuous software management, FireWire 800 efficiently delivers more than 97 percent of its bit rate as payload -- not overhead. FireWire 800 hard drives today can easily move over 90 megabytes per second. S3200 preserves 100 percent of the 1394b design efficiency and will deliver extremely high payload speeds reaching nearly 400 megabytes per second. Other interface technologies struggle to deliver half their advertised bit rate to the user, even under optimal conditions.
No Compromises to 1394’s Features
The S3200 specification brings FireWire to this new performance level without compromising existing features. For example, FireWire provides much more electrical power than any other interface, freeing users from inconvenient AC power adapters. FireWire products built using S3200 will directly connect to every previously released FireWire product. Alternative cable options are available to carry FireWire over long distances - 100 meters or more - even at high speeds.
Also, FireWire’s peer-to-peer architecture allows products to operate with a computer - or without one. This superior combination of features is not found in any other technology, which explains why over one billion FireWire ports have been shipped to date, on products as diverse as computers, cameras, televisions, hard drives, and musical instruments. IEEE 1394 also is deployed in vital applications in state-of-the-art aircraft and polar orbiting satellites.
S3200 Strengthens 1394’s Position in Storage, Consumer Electronics
One of the strongest markets today for FireWire is storage for computers. The best hard drives with FireWire 800 can move data almost three times as fast as the best hard drives with USB 2.0. Also, FireWire provides much more electrical power than USB, so FireWire-equipped hard drives can operate without an AC adapter, and at high rotational speeds. USB hard drives can fail to work from USB power, or require a second USB cable for power, or use the lowest-performance drive mechanisms because so little power is available.
With S3200 this power advantage for FireWire is fully preserved. S3200 also makes FireWire so fast that users will see no advantage from eSATA. Both interfaces are much faster than any modern hard drive mechanism, but eSATA does not provide electrical power to operate a drive. On a computer, an eSATA port is far less flexible than a FireWire port, because many more devices can connect to FireWire. For these reasons, S3200 makes FireWire the superior choice for future external storage products.
S3200 will also enhance FireWire’s strong position in consumer electronics A/V devices such as camcorders and televisions. Today, 100 percent of HD set top boxes provided by cable companies have FireWire ports. So do 100 models of HDTV. FireWire is the only separable interface today that can record HD programs in their full digital quality while also meeting the content protection requirements of copyright holders. Many companies are pursuing whole-home HD network solutions using FireWire - notably the HANA Alliance.
Technology development is also nearing completion to permit FireWire to operate over cable television coaxial cables, without disrupting the existing program content. With S3200, FireWire becomes fast enough to move even uncompressed HD signals over long distances at much lower cost than solutions such as HDMI.
"The S3200 standard will sustain the position of IEEE 1394 as the absolute performance leader in multi-purpose I/O ports for consumer applications in computer and CE devices," said James Snider, executive director, 1394 Trade Association. "There is a very clear migration path from 800 Megabits/second to 3.2 Gigabits/second, with no need for modifications to the standard and no requirement for new cables or connectors."
The Silicon Working Group developed the S3200 specification within the 1394 Trade Association, with participation by industry leaders including Symwave, Texas Instruments, LSI Corporation, and Oxford Semiconductor. S3200 specifies the electrical operation of the 3.2 Gigabit mode first specified by IEEE 1394b-2002, without changing any connector, cable, protocol, or software requirements. Based on the working group's progress, the Trade Association has set a January 2008 date for the specification to enter a ratification process.
