1394 Trade Association


The official industry consortium behind 1394 technology. They house specifications for AV/C and other stuff.

Don't miss their great 1394 Standards and Specifications Summary.

IEEE 1394

IEEE Std 1394-2008


From the 1394 TA's press release: "The 1394-2008 High Performance Serial Bus Standard updates and revises all prior 1394 standards dating back to the original 1394-1995 version, and including 1394a, 1394b, 1394c, enhanced UTP, and the 1394 beta plus PHY-Link interface. It also incorporates the complete specifications for S1600 (1.6 Gigabit/second bandwidth) and for S3200, which provides 3.2 Gigabit/second speeds."

IEEE Std 1394-1995

IEEE standard for a high performance serial bus

IEEE Std 1394a-2000


IEEE Standard for a high Performance Serial Bus - Amendment 1. A lot of the IEEE 1394a updates are relevant to programmers.

IEEE Std 1394b-2002


IEEE Standard for a High-Performance Serial Bus - Amendment 2. Defines S100B...S1600B transmission modes over copper and optical fibre. Only very few details of this huge update to IEEE 1394 are relevant to programmers.

IEEE Std 1394c-2006


IEEE Standard for a High-Performance Serial Bus - Amendment 3. Defines S800T, an 800 Mbit/s transmission mode over gigabit Ethernet copper. Probably not (yet) relevant to programmers.

IEEE Std 1394.1-2004


IEEE Standard for High Performance Serial Bus Bridges. Defines bridging devices which connect separate FireWire buses. No implementations are known. The Linux drivers don't have explicit support for 1394.1 yet but should at least be prepared to deal with bus IDs other than the local bus.

IEEE 1212

IEEE Std 1212-2001


IEEE standard for a control and status registers (CSR) architecture for microcomputer buses. IEEE 1394 is an implementation of IEEE 1212 (the most important one, and the only one besides SCI, Scalable Coherent Interface). IEEE 1212 especially defines the format and generic contents of the configuration ROM.

ISO/IEC 13213: 1994(E), ANSI/IEEE Std 1212, 1994 Edition


This was revised and hence superseded by IEEE 1212-2001.

1394 Open Host Controller Interface Specification

OHCI Release 1.00, October 20, 1997

Some controllers, e.g. VIA VT6306 which is still in production, only support OHCI 1.0 instead of the more current OHCI 1.1.

OHCI Release 1.1, January 6, 2000



Look here for the most in-depth technical information about IEEE 1394 technology, at least as it applies to OHCI. This spec is gratis, whereas the IEEE specifications have to be purchased.

OHCI 1.1 especially adds dual-buffer reception.

OHCI Release 1.2

Among else, this was apparently supposed to update OHCI for 1394b. But this spec was never finished. Currently available 1394b host adapters implement OHCI 1.1 or a superset of it.

PCILynx datasheets

SCPA020A — PCILynx 1394 to PCI Bus Interface TSB12LV21BPGF Functional Specification

SLLA023 — Initialization and Asynchronous Programming of the PCILynx TSB12LV21A 1394 Device

PCILynx is an older 1394 PCI controller which is not OHCI compliant.

The Serial Bus Protocol


This is obsolete and practically irrelevant.



Serial Bus Protocol 2 is a SCSI transport protocol but can also be used to transport commands of non-SCSI command sets. All of the FireWire storage devices (harddisks, CD/DVD-ROM/R/W, card readers, scanners, ...) implement SBP-2 and typically one or another SCSI command set such as RBC or MMC.



This version adds isochronous support to Serial Bus Protocol, particularly for A/V applications. It also adds support for remote buses behind 1394.1 bridges. There are no devices known to implement SBP-3.

Other SCSI specifications and working drafts


Instrumentation and Industrial Control Digital Camera (IIDC) Specification



http://1394ta.org/press/TAPress/2008_1027.html (announcement of v1.32 release and work on v2.0)

This specification covers uncompressed video and camera control (focus, format, pan, zoom, white balance, etc.). Also known as DCAM.
