Description

Full Description

Scope

This project will amend the existing 1394-1995 and 1394a-2000 standards to include: a) cables and connectors for gigabit signaling and long distance (up to 100 meters); b) detection of physical loops in the bus topology and their subsequent resolution by selective disabling of PHY port(s); c) circuit design that permits the transmission either data/strobe encoded signals or 8B10B encoded signals; d) extension of the PHY/link interface for higher data rates over either an 8-bit parallel or bit-serial bus; f) protocols to encode bus arbitration signals as symbols; f) a method to encapsulate lower speed transmissions within packets transmitted at the buses maximum operating speed; g) protocols for signal speed negotiation between peer devices at the time the connection is detected; h) port initialization protocols suitable for use over AC coupled connections; and i) various informative annexes that describe testing and compliance procedures for gigabit connections.

Purpose

Technology advances have made gigabit signaling a feasible and attractive extension to the original Serial Bus standard. In particular, the needs of mass storage and home network backbones require higher speeds and longer distances than are specified by IEEE Std 1394-1995 as amended by IEEE Std 1394a-2000.

Abstract

Amendment Standard - Superseded. Supplemental information for a high-speed serial bus that integrates well with most IEEE standard 32-bit and 64-bit parallel buses is specified. It is intended to extend the usefulness of a low-cost interconnect between external peripherals. This standard follows the IEEE Std 1212 ¿¿¿-2001 Command and Status Register (CSR) architecture.
