High-Performance PCI Express 2-Port IEEE 1394A Expansion Card W-1394A-PCIE

PCI Express to IEEE 1394a Expansion Solution

The W-1394A-PCIE PCI Express 2-Port IEEE 1394A card is designed to add two IEEE 1394a-2000 compliant cable ports to a compatible computer system. At the center of the card is the Texas Instruments XIO2200A, a single-function PCI Express-to-PCI local bus translation bridge.

The PCI bus interface is internally connected to a 1394a-2000 open host controller link-layer controller with a two-port 1394a PHY. When the XIO2200A is properly configured, the solution provides complete PCI Express and IEEE 1394a functionality and performance.

For B2B buyers maintaining or extending computer systems that require IEEE 1394a connectivity, the W-1394A-PCIE provides clearly defined interface specifications, transfer rates, standards compliance, and operating system support for easier compatibility evaluation before purchasing.

Key Specifications of W-1394A-PCIE

PCI Express Performance and Architecture

The W-1394A-PCIE supports full x1 PCI Express throughput and is fully compliant with the PCI Express Base Specification, Revision 1.0a.

The architecture provides a second virtual channel for Quality-of-Service and isochronous applications, giving the controller additional flexibility for applications involving defined traffic classes. Advanced PCI isochronous windows support memory-space mapping to a specified traffic class.

The controller utilizes either a 100 MHz differential PCI Express common reference clock or a 125 MHz single-ended reference clock, according to the system configuration.

Its two-port architecture also provides procurement and engineering teams with a straightforward specification when evaluating expansion cards for systems requiring more than one IEEE 1394a cable connection.

Full IEEE 1394a-2000 Support

On the IEEE 1394 side, the W-1394A-PCIE is fully compliant with provisions of IEEE Std 1394-1995 for a High-Performance Serial Bus and IEEE Std 1394a-2000.

Both IEEE 1394a cable ports support three data transfer rates:

• 100 Mbit/s

• 200 Mbit/s

• 400 Mbit/s

IEEE 1394a-2000 functionality includes connection denounce, arbitrated short reset, multiplexed concatenation, arbitration acceleration, fly-by concatenation, and port disable, suspend, and resume functions.

The solution is also fully compliant with the 1394 Open Host Controller Interface Specification, Revision 1.1, helping buyers evaluate the product according to established IEEE 1394 host controller requirements.

EEPROM configuration support is provided to load the Global Unique ID for the 1394 fabric.

The original product specification also lists “Serial ATA Interface” under its software/features section. This wording is retained from the supplied technical information and should not be interpreted as confirmation of additional external SATA connectors.

Operating System Support

For procurement projects involving legacy computer platforms, buyers should compare the operating system, motherboard PCI Express interface, required IEEE 1394a transfer speed, and connected equipment requirements before placing an order.

Packaging and Carton Information

For distributors, importers, and volume purchasers, carton information is an important part of freight and warehouse planning.

These specifications can help procurement teams calculate carton quantities, shipment volume, warehouse requirements, and logistics costs during quotation evaluation.

Why Consider the W-1394A-PCIE?

The W-1394A-PCIE combines a PCI Express x1 host interface, Texas Instruments XIO2200A controller, two IEEE 1394a ports, and transfer rates up to 400 Mbit/s in one expansion solution.

Its clearly specified PCI Express, IEEE 1394a, and OHCI compliance makes it suitable for buyers who need to compare expansion-card specifications with existing system requirements before sourcing replacement or system-extension components.
