1394a Consumer Electronic Devices More Information

Technology Overview www.ti.com/1394 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). 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 More Information

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 More Information

(ü) for new gener-ation POF 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   Reach S100 S200 S400 S800 S1600 S3200 UTP5 100m  POF/ HPCF  only 50m for POF (ü) for new gener-ation POF MMF       (ü)   STP (Beta) 4.5m (ü) STP (DS) Higher speeds defined to 4 Gbps raw More Information

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) More Information

Better with 1394b: More Efficient New asynchronous arbitration (BOSS) Overlapped, pipelined arbitration Asynchronous Performance, taken with TI TSB82AA2 LLC + TI TSB81BA3 + Unibrain SW stack & test application More Information

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 More Information
