It allows for transparent and inverted transparent modes of data transfer with separate LVTTL input and LVTTL output pins, which provides a feedback path for control and diagnostics monitoring. The device provides a high-speed interface between cards operating at LVTTL logic levels and a backplane operating at GTLP signal levels, and is especially designed to work with the Texas Instruments (TITM) 1394 backplane physical-layer controllers. High-speed (about three times faster than standard LVTTL or TTL) backplane operation is a direct result of GTLP reduced output swing ( VCC. The package thermal impedance is calculated in accordance with JESD 51-7. The package thermal impedance is calculated in accordance with JESD 51-5. www.ti.com SN74GTLP1394 SN74GTLP1394 2-BIT LVTTL-TO-GTLP ADJUSTABLE-EDGE-RATE BUS TRANSCEIVER WITH SPLIT LVTTL PORT, FEEDBACK PATH, AND SELECTABLE POLARITY SCES286F SCES286F ­ OCTOBER 1999 ­ REVISED APRIL 2005 Recommended Operating Conditions (1) (2) (3) (4) MIN VCC, BIAS VCC Termination voltage VREF Reference voltage VI Input voltage VIH High-level input voltage MAX UNIT 3.15 3.3 3.45 V GTL 1.14 1.2 1.26 GTLP 1.35 1.5 1.65 GTL 0.74 0.8 0.87 GTLP 0.87 1 1.1 Supply voltage VTT NOM B port VTT Except B port B port ERC Except B port and ERC VCC 5.5 VCC 5.5 Low-level input voltage IIK VCC ­ 0.6 High-level output current IOL Low-level output current t/v Input transition rise or fall rate t/VCC Power-up ramp rate TA Operating free-air temperature (2) (3) (4) V VREF ­ 0.05 ERC GND Except B port and ERC (1) V 2 Input clamp current IOH V VREF + 0.05 B port VIL V 0.6 V 0.8 ­18 Y outputs mA ­24 Y outputs mA 24 B port 100 Outputs enabled 10 ns/V µs/V 20 ­40 mA 85 °C All unused inputs of the device must be held at VCC or GND to ensure proper device operation. Refer to the TI application report, Implications of Slow or Floating CMOS Inputs, literature number SCBA004 SCBA004. Proper connection sequence for use of the B-port I/O precharge feature is GND and BIAS VCC = 3.3 V first, I/O second, and VCC = 3.3 V last, because the BIAS VCC precharge circuitry is disabled when any VCC pin is connected. The control and VREF inputs can be connected anytime, but normally are connected during the I/O stage. If B-port precharge is not required, any connection sequence is acceptable, but generally, GND is connected first. VTT and RTT can be adjusted to accommodate backplane impedances if the dc recommended IOL ratings are not exceeded. VREF can be adjusted to optimize noise margins, but normally is two-thirds VTT. TI-OPC circuitry is enabled in the A-to-B direction and is activated when VTT > 0.7 V above VREF. If operated in the A-to-B direction, VREF should be set to within 0.6 V of VTT to minimize current drain. 5 SN74GTLP1394 SN74GTLP1394 2-BIT LVTTL-TO-GTLP ADJUSTABLE-EDGE-RATE BUS TRANSCEIVER WITH SPLIT LVTTL PORT, FEEDBACK PATH, AND SELECTABLE POLARITY www.ti.com SCES286F SCES286F ­ OCTOBER 1999 ­ REVISED APRIL 2005 Electrical Characteristics over recommended operating free-air temperature range for GTLP (unless otherwise noted) PARAMETER MIN TYP (1) MAX TEST CONDITIONS VIK VCC = 3.15 V, VCC = 3.15 V to 3.45 V, VOH Y outputs II = ­18 mA IOH = ­100 µA VCC ­ 0.2 IOH = ­12 mA 2.4 IOH = ­24 mA 2 VCC = 3.15 V VCC = 3.15 V 0.5 IOL = 10 mA B port 0.4 IOL = 24 mA VOL 0.2 IOL = 12 mA VCC = 3.15 V 0.2 A-port and control inputs IOZH (2) Y outputs IOL = 64 mA VCC = 3.45 V, ICC Y outputs and B port VCC = 3.45 V, IO = 0, VI (A-port or control inputs) = VCC or GND, VI (B port) = VTT or GND 10 VO = GND Y outputs and B port ­10 Outputs high A-port inputs Control inputs 20 Y outputs 3.5 B port VO = 1.5 V or 0 (1) (2) (3) mA 4.5 4 VO = 3.15 V or 0 Cio mA 1.5 VI = 3.15 V or 0 Co µA 20 Outputs disabled µA 20 Outputs low VCC = 3.45 V, One A-port or control input at VCC ­ 0.6 V, Other A-port or control inputs at VCC or GND ICC (3) µA 10 VO = 1.5 V IOZL (2) Ci ±10 VO = VCC VCC = 3.45 V B port 0.55 VI = 0 to 5.5 V VCC = 3.45 V, V 0.4 IOL = 100 mA II V V IOL = 100 µA VCC = 3.15 V to 3.45 V, Y outputs UNIT ­1.2 5 pF 4.5 5 pF 9 10.5 pF All typical values are at VCC = 3.3 V, TA = 25°C.

But, it is a versatile 2-bit device that also is being used to provide multiple single-bit clocks or an ATM read and write clock in multislot parallel backplane applications. The 1394-1995 is an IEEE designation for a high-performance serial bus. This serial bus defines both a backplane (e.g., GTLP, VME, FB+, CPCI, etc.) physical layer and a point-to-point cable-connected virtual bus. The backplane version operates at 25, 50, or 100 Mbps, whereas the cable version supports data rates of 100, 200, and 400 Mbps. Both versions are compatible at the link layer and above. The interface standard defines the transmission method, media in the cable version, and protocol. The primary application of the cable version is the interconnection of digital A/V equipment and integration of I/O connectivity at the back panel of personal computers using a low-cost, scalable, high-speed serial interface. The primary application of the backplane version is to provide a robust control interface to each daughter card. The 1394 standard also provides new services, such as real-time I/O and live connect/disconnect capability for external devices. Electrical The 1394 standard is a transaction-based packet technology for cable- or backplane-based environments. Both chassis and peripheral devices can use this technology. The 1394 serial bus is organized as if it were memory space interconnected between devices, or as if devices resided in slots on the main backplane. Device addressing is 64 bits wide, partitioned as ten bits for bus ID, six bits for node ID, and 48 bits for memory addresses. The result is the capability to address up to 1023 buses, with each having up to 63 nodes, each with 281 terabytes of memory. Memory-based addressing, rather than channel addressing, views resources as registers or memory that can be accessed with processor-to-memory transactions. Each bus entity is termed a unit, to be individually addressed, reset, and identified. Multiple nodes can reside physically in a single module, and multiple ports can reside in a single node. Some key features of the 1394 topology are multimaster capabilities, live connect/disconnect (hot plugging) capability, genderless cabling connectors on interconnect cabling, and dynamic node address allocation as nodes are added to the bus. A maximum of 63 nodes can be connected to one network. The cable-based physical interface uses dc-level line states for signaling during initialization and arbitration. Both environments use dominant mode addresses for arbitration. The backplane environment does not have the initialization requirements of the cable environment because it is a physical bus and does not contain repeaters. Due to the differences, a backplane-to-cable bridge is required to connect these two environments. The signals transmitted on both the cable and backplane environments are NRZ with data-strobe (DS) encoding. DS encoding allows only one of the two signal lines to change each data bit-period, essentially doubling the jitter tolerance, with very little additional circuitry overhead in the hardware. 11 SN74GTLP1394 SN74GTLP1394 2-BIT LVTTL-TO-GTLP ADJUSTABLE-EDGE-RATE BUS TRANSCEIVER WITH SPLIT LVTTL PORT, FEEDBACK PATH, AND SELECTABLE POLARITY www.ti.com SCES286F SCES286F ­ OCTOBER 1999 ­ REVISED APRIL 2005 APPLICATION INFORMATION Protocol Both asynchronous and isochronous data transfers are supported. The asynchronous format transfers data and transaction-layer information to an explicit address. The isochronous format broadcasts data based on channel numbers, rather than specific addressing. Isochronous packets are issued on the average of each 125 µs in support of time-sensitive applications. Providing both asynchronous and isochronous formats on the same interface allows both non-real-time and real-time critical applications on the same bus. The cable environment's tree topology is resolved during a sequence of events, triggered each time a new node is added or removed from the network. This sequence starts with a bus reset phase, where previous information about a topology is cleared. The tree ID sequence determines the actual tree structure, and a root node is dynamically assigned, or it is possible to force a particular node to become the root. After the tree is formed, a self-ID phase allows each node on the network to identify itself to all other nodes. During the self-ID process, each node is assigned an address. After all the information has been gathered on each node, the bus goes into an idle state, waiting for the beginning of the standard arbitration process. The backplane physical layer shares some commonality with the cable physical layer. Common functions include: bus state determination, bus access protocols, encoding and decoding functions, and synchronization of received data to a local clock.

Specified bandwidth assignments for real-time applications Applicability and Typical Application for IEEE Std 1394 Backplane The 1394 backplane serial bus (BPSB) plays a supportive role in backplane systems, specifically GTLP, FutureBus+, VME64 VME64, and proprietary backplane bus systems. This supportive role can be grouped into three categories: · Diagnostics ­ Alternate control path to the parallel backplane bus ­ Test, maintenance, and troubleshooting ­ Software debug and support interface · System enhancement ­ Fault tolerance ­ Live insertion ­ CSR access ­ Auxiliary 2-bit bus with a 64-bit address space to the parallel backplane bus · Peripheral monitoring ­ Monitoring of peripherals (disk drives, fans, power supplies, etc.) in conjunction with another externally wired monitor bus, such as defined by the Intelligent Platform Management Interface (IPMI) The 1394 backplane physical layer (PHY) and the SN74GTLP1394 SN74GTLP1394 provide a cost-effective way to add high-speed 1394 connections to every daughter card in almost any backplane.
