1394 High Performance Serial Bus, also known as Firewire,
is a versatile, high-speed, and low-cost method of
transferring digital data between personal computer peripherals and consumer electronics devices. IEEE
1394 can transport data at 100/200/400 Mbps.
Digital interface - no need to convert digital data
into analog and then digital again for processing,
which will have a loss of data integrity.
- thin serial cable will replace large and more
to use - no terminators, devices ID etc¡K
plugable for plug and play applications
- the high volume consumer market will achieve low-cost
1. Consumer electronics devices (up to 100 Mbps)

Professional and industrial market (up to 400Mbps)
for the 8-bit parallel bus of the IEEE 488 Standard
Digital interface for Programmable Instrumentation.
transmission of 10-bit uncompressed digital video
and several simultaneous channels of 16-bit, 48kHz
stereo digital audio.
definition (HD, 16:9) digital input TV set (221Mbps
for 30 frames/sec, 640x480 pels & 24-bit color/pel)
Cable Plug Connector
fully shielded connector will have six contacts. The
contact design creates a Hertzian stress (combination
of cylindrical radius, normal force, base and surface
material hardness) of 225,000 - 275,000 psi in the
mating area. The connector plug termination can be
made by crimp, insulation displacement (ICD), insulation
piercing & soldering.
cable consists of two twisted pairs (signal pair)
& two power connectors. The signal pair carries the
balanced differential data signal, while the power
conductors carries the bus power (about 8~40 VDC).
signal pair will have individual braid (60~65%) shield.
The overall cable has a outer shield (90~95% braid
copper wire over spiral wrap metallized polyester
tape, with the metal to the outside)
cable assembly consists of two identical plug connectors
jointed by a cable (Maximum length is 4.5m). When
a cable assembly plug is mated with a socket connector,
there should be 1 mm (minimum) clearance between overmold
on the assembly plug & the shield flange on the socket.
