Technology Overviewwww.ti.com/1394

1394b-2002 Advantages • Faster: speeds from 800 Mbps

to 3200 Mbps • Longer distances: 100

meters with GOF and Cat5; 50 meters with POF

• TI 1394b 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

General Description: The IEEE 1394 (FireWire™) high-speed interconnection enables simple, low-cost, high-bandwidth real-time data connectivity between computers, peripherals and consumer electronics. Today, all major PC makers provide customers with the option of adding 1394 to both desktop and notebook PCs. 1394b is an extension of earlier 1394 technology that enables higher performance (up to 3.2 Gbps), longer distance (up to 100 meters) and a variety of cable media to fit any application (STP, UTP, POF, GOF).

What is the Same as 1394a?

• Logical bus model• Peer-to-peer operation• User friendly Ease of Use – Plug

and Play• Transaction and addressing

models• Asynchronous and Isochronous

operation models (QOS)• Power management (with one new

mode)• Hybrid Bus Operation

– A 1394b port may be implemented as:

• Data–strobe port (1394a–only)• Beta–mode only port (1394b–

only)• A bilingual portAny mix of 1394

DS & beta ports allowed– Connector keying ensures that

incompatible connections cannot physically be made

• What “Same” Means– Identical functionality above the

LLC • SW can mostly be used as-is

– Change required for Self-ID / Speed detection or Bus optimization

– Changes needed to use faster rates, larger packets, additional power management modes

– LLCs may be used as-is• Changes needed for faster rates,

larger packets and more efficient arbitration

– PHY Layers MUST change• But may be made 1394a-

compatible• Should be Bilingual to connect

with millions of existing 1394 devices in market today

Better with 1394b

• 800Mbps available today• 3200Mbps specified• Parallel Link/PHY interface can be

either:– 1394a

• up to 8 data lines & 1 clock at 50MHz

– 1394b• 8 data lines & 2 clocks at 100MHz

• Longer distance requires new media– Unshielded Twisted Pair CAT5 for

S100• Just like 100BASE-T Ethernet

– Plastic Optical Fiber (POF) or Hard Polymer Clad Fiber (HPCF) for S200(+?)

• S400 has been demonstrated

– Multi-mode glass fiber (MMF) for higher speeds

Better with 1394b: Copper STP

• New connector needed for higher 1394b data rates

– Designed for both CE and PC worlds• Only slightly larger than existing 4-ckt

connector• Carries power to support PC

peripherals

• Keying to ensure compatibility– Beta mode signaling is never used on

a Legacy connector– Simplifies backwards compatibility

• Two PWB socket variants– Bi-lingual connector

• accepts bilingual plug or Beta plug– Beta connector

• only accepts Beta plug

• Bilingual And Beta Connector Plugs– 9 pin

• Include power• 2 extra pins for signal integrity• One pin reserved for future use

– Small size - mating interface 8mm x 5 mm

• 3 Cables, 4 Sockets– Legacy mode cables (prevents DS to

Beta-only connection)• Bilingual to 6-ckt DS (carries power)• Bilingual to 4-ckt DS (no power)

– Beta mode cable (also used for bilingual to Beta)

Implications of Better

• Data throughput increase– Throughput bottlenecks

• S800 host controller may source/sink 100 MB/s– HDDs may stress throughput

– Host System Interface Options• 32/33 PCI 133 MB/s max

– S800 possible on 32/33 PCI but may limit performance– May not be sufficient for multiple real time streams

• 64 bit, 66 MHz PCI, or PCI-X– Better choice for supporting higher bandwidth

• Raw bit rate increase affects Signal Integrity– 62.5MHz to 2GHz with fast rise times

• critical etch length– Same story as 1394a, RAMBUS, InfiniBand, USB2.0, DVI, and now

1394b.– Very difficult to “add in” later, must be designed in early
