Standard for a High-Performance Serial Bus

This standard describes a high-speed, low-cost serial bus suitable for use as a peripheral bus, a backup to parallel backplane buses, or a local area network. Highlights of the serial bus include the following: a)Bus transactions that include both block and single quadlet reads and writes, as well as an "isochronous" mode that provides a low-overhead guaranteed bandwidth service. b)A fair bus access mechanism that guarantees all nodes equal access. The backplane environment adds a priority mechanism, but one that ensures that nodes using the fair protocol are still guaranteed at least partial access. c)Automatic assignment of node addresses--no need for address switches. d)A physical layer (PHY) supporting both long-haul and short-haul cable media and backplane buses. e)Variable speed data transmission based on ISDN-compatible1 bit rates from 24.576 Mbit/s for transistor-transistor logic (TTL) backplanes to 49.152 Mbit/s for backplane transceiver logic (BTL) backplanes. For the cable medium, data transmission rates of 98.304 Mbit/s (known as S100), S200, S400, S800, S1600, and S3200 are supported. f)A short-haul cable medium that allows up to 16 physical connections (cable hops), each up to 4.5 m, giving a total cable distance of 72 m between any two devices. Bus management recognizes smaller configurations to optimize performance. g)A long-haul cable medium that permits connections up to 100 m in length over unshielded twisted pair (UTP) cable and glass optical fiber (GOF) and up to 50 m over plastic optical fiber (POF). h)Consistency with ISO/IEC 13213:1994 (IEEE Std 1212(TM), 1994 Edition).

These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.


1394-1995

IEEE Standard for a High Performance Serial Bus

A high-speed serial bus that integrates well with most IEEE standard 32-bit and 64-bit parallel buses, as well as such nonbus interconnects as the IEEE Std 1596-1992, Scalable Coherent Interface, is specified. It is intended to provide a low-cost interconnect between cards on the same backplane, cards on other backplanes, and external peripherals. This standard follows the IEEE Std 1212-1991 Command and Status Register (CSR) architecture.

1394a-2000

IEEE Standard for a High Performance Serial Bus (Amendment)

Amended information for a high-speed Serial Bus that integrates well with most IEEE standard 32-bit and 64-bit parallel buses is specified. This amendment is intended to extend the usefulness of a low-cost interconnect between external peripherals, as described in IEEE Std 1394-1995. This amendment to IEEE Std 1394-1995 follows the ISO/IEC 13213:1994 Command and Status Register (CSR) Architecture.

These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.


No Inactive-Withdrawn Standards

These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.


1394-2008

IEEE Standard for a High-Performance Serial Bus

This standard provides specifications for a high-speed serial bus that supports both asynchronous and isochronous communication and integrates well with most IEEE standard 32-bit and 64-bit parallel buses. It is intended to provide a low-cost interconnect between cards on the same backplane, cards on other backplanes, and external peripherals. Interfaces to longer distance transmission media [such as unshielded twisted pair (UTP), optical fiber, and plastic optical fiber (POF)] allow the interconnection to be extended throughout a local network. This standard follows the command and status register (CSR) architecture of IEEE Std 1212-2001.
