IEEE 1394 -1995

IEEE Standard for a High Performance
Serial Bus
1. Overview
1.1 Scope
This standard describes a high-speed, low-cost Serial Bus suitable for use as a peripheral bus or a backup to parallel
backplane buses. Highlights of the Serial Bus include
a) Automatic assignment of node addresses—no need for address switches.
b) Variable speed data transmission based on ISDN-compatible1 bit rates from 24.576 Mbit/s for TTL
backplanes to 49.152 Mbit/s for BTL backplanes to 98.304 Mbit/s, 196.608 Mbit/s, and 393.216 Mbit/s for
the cable medium.
c) The cable medium allows up to sixteen 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.
d) 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.
e) A physical layer supporting both cable media and backplane buses.
f) 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.
g) Consistent with ISO/IEC 13213 :1994 (IEEE Std 1212-1991).
