Senior Design 4006C Group G7 Background Report 1394b – Receiver The new generation of FireWire. Luke Starnes (gte874d) Aparna Trimurty (gt9794a) Jeff Schlipf (gte877e)

Background - 1394 1986 – Apple started FireWire IEEE 1394-1995 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

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.

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

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)

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

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.

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.

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 Create working Gigabit 1394 module Test BER, Jitter, and Eye mask need BER<10-12 Use receiver/post-amp kits to replace OE module interface with the transmitter and OE groups Design our own board
