Technical Information (Continued)

Applications of the cable version are the integration of I/O connectivity of personal computers, peripherals, and consumer electronics using a low-cost, scalable, high-speed serial interface. The 1394 standard provides services such as real- time I/O and live connect/disconnect capability for devices including storage (HDD, CD-ROM, CDRW, MO, ZIP, RAID, SAN, etc.), printers, scanners, cameras, set-top boxes, HDTVs and camcorders.

Key Features

Real-time streaming of audio and video

High-speed: up to 400 Mbps with IEEE 1394-1995 and 1394a-2000, up to 1, 2 and 4 Gbps with 1394b

Plug-and-play hot pluggable

Peer-to-peer communication

Small, durable and flexible cable and connectors

Memory-mapped architecture

Seamless I/O interconnect

1394b Advantages

Faster: speeds from 800 Mbps to 3200 Mbps

Longer distances: 100 meters with GOF and CAT5; 50 meters with POF

TI1394b is bi-lingual: communicates in 1394a and 1394b modes

More cabling options: STP, CAT5, POF, GOF

More efficient: BOSS arbitration

More user-friendly: loop-free build allows any topology and redundancy
