2. Background - 1394 1986 – Apple started FireWire
IEEE accepted on December 12, 1995
IEEE 1394a accepted in 2000
Late 1996 work began on new standard – 1394b
Draft for 1394b submitted to IEEE in 2001
•1986 – Apple started FireWire
1394 was based on this design
• IEEE 1395 (adapted from Apple’s original design) accepted December 12, 1995
name from fact 1393 drafts were submitted
IEEEa accepted in 2000
too many holes in 1995 standard. Too much leniency -> too much variation
better arbitration
Late 1996 work began on new standard – 1394b (further and faster)
Draft for 1394b submitted to IEEE in 2001

3. Future of Home Networking
As you can see with 1394b we will be able to completely interconnect our PC’s with our AV equipment.
The last 50 feet of the Information Super Highway.

4. 1394 – Why was it created? Digital connection for digital devices
More bandwidth
Isochronous
Digital connection for digital devices
as A/V went digital there was still a loss b/c cables were analog so a D/A and A/D were needed on devices to allow interconnection
More bandwidth
than USB. A/V devices needed more BW
Isochronous
guaranteed BW for AV dev
NO lag – like ethernet

5. 1394 – Advantages over competition
Versatility
High Speed
Isochronous
Low Cost
User Friendly
Peer-to-Peer
All Digital
Includes power for device in cable
Versatility
variable speeds
No Hubs – you daisy chain
up to 63 devices on 1 bus
High Speed
up to 400 Mbps
Isochronous
great for AV
guaranteed bandwidth – no lag
Low Cost
made for consumer products
User Friendly
Hot swappable
PnP
Peer-to-Peer
no need for PC
All Digital
no need for A/D and D/A
Includes power for device in cable
there are 2 sets of twisted pair wires and a set of power wires (delivering up to 1.5 Amps)

6. 1394a – Specifications Speeds up to 400Mbps 4.5 meter cable

7. 1394b – Advantages over 1394a Further and Faster. Cost Reduction.
Smaller connector.
Goes Further, Faster.
Cost reductions over the existing 1394 implementations are possible since the new "pure beta" (not backward compatible) mode specified by P1394b allow simple galvanic isolation, greatly reducing the complexity of the analog circuitry and allowing simple integration of the PHY and Link components.
The "pure beta" copper connector is almost as small as the existing 4-pin connector, yet is capable of carrying power, indicating speed capabilities of the media, and is capable of carrying a full 3.2 Gbit/sec signal.

8. 1394b – Specifications Speeds up to 1.6 Gbps Up to 100 meters of cable
Added 800 and 1600 as speeds (also 3200 is in architecture for the future)
Node-to-node distances to over 100m using various media. 100 Mbps is supported for category 5 unshielded twisted pair (CAT-5 UTP), 200 Mbps over plastic optical fiber, and a full 3.2 Gbps using 50 µm multimode glass fiber.
supports optical cable lengths of 50 meters for plastic optical fiber and 100 meters for glass optical fiber.

9. Project Goals Create working Gigabit 1394 module
Test BER, Jitter, and Eye mask
Use receiver/post-amp kits to replace OE module
Design our own board
