Leading Communications IC Company Delivers High-Performance Switches and Bridges Optimized for Server and Storage Applications
February 28, 2005

Santa Clara, Calif., February 28, 2005 — IDT(Integrated Device Technology, Inc.; NASDAQ:  IDTI) today demonstrated proof of its commitment to standards-based serial switching with the introduction of its PRECISE™ family of PCI Express™ solutions, consisting of four bridging and switching products.  Aimed at high-performance server and storage applications, the PRECISE family of bridging and switching solutions will be the first to provide cost-effective PCI Express I/O expansion and bridging solutions.  IDT will also offer customers a complete hardware/software development kit that includes evaluation boards, software drivers and a graphical user interface (GUI) that enables complete system configuration and optimization.  The solutions will be offered at price points that meet the needs of mainstream server and storage system OEMs, with the intent of lowering the overall cost per Gigabyte of switching.

“Alternative PCI Express bridging and switching devices have taken the form of general-purpose devices – they provide a host of features to service a myriad of applications, most of which are not necessary in today’s high-performance computing and storage applications,” said Mario Montana, director of marketing for the IDT serial-switching division.  “The result is an over-architected, expensive device.  We have worked closely with our customers over the past year to apply our switching systems expertise and software proficiency to develop optimized solutions that meet the critical needs of the server and storage markets.”

According to Ernie Bergstrom, principal analyst at Crystal Cube Consulting, “The introduction of IDT’s bridging and switching products helps validate the evolving PCI Express landscape.  In order to meet the total available market potential of standards-based bridging and switching solutions, expected to reach 1.8 billion in port shipments by year-end 2007, it will take well-established companies with proven product development and delivery track records, such as IDT, joining the mix.”


“Intel has been a long-time proponent of standards-based serial switching because it leads to broader, more cost-effective adoption of the latest technology,” said Jim Pappas, director of initiative marketing for Intel’s Digital Enterprise Group.  “With companies such as IDT now delivering products that support PCI Express, enterprise server and storage equipment makers will be able to provide cost-effective I/O expansion and bridging solutions.”


IDT PRECISE PCI Express Bridging and Switching Solutions

The company’s initial family of PRECISE PCI Express bridging and switching solutions includes four devices, which are all backwards compatible to PCI-X standards.


IDT is offering two 3-port PCI Express switches, including 12-lane and 24-lane devices.  The IDT PCI- Express switches provide I/O expansion to augment “north bridge” devices with additional high-performance I/O connectivity.

The PRECISE family also includes a PCI Express to PCI-X 2.0 mode 1 bridge and a PCI Express to PCI-X 2.0 mode 2 bridge.  The PCI Express to PCI-X 2.0 mode 2 bridge is the first of its kind and is an ideal solution for high-performance server applications.  These devices bridge high-performance PCI Express ports to legacy peripherals, enabling designers to maintain CPU performance while leveraging existing and commoditized peripherals with legacy interfaces.  This process is commonly referred to as “forward bridging.”  The devices also aid in the task of “reverse bridging” – acting as an interface between legacy north bridge ports, typically in the form of PCI-X, to newer PCI Express-based peripherals.

Hardware and Software Development Support
Each IDT PRECISE PCI Express bridging and switching solution will be supported with an optimized hardware/software development kit, which contains several components.  A hardware evaluation board is customized for product demonstrations, software development and initial system-performance benchmarking.  Boardform factors and specifications will enable interfacing to off-the-shelf components for robust system emulation.  The development kit also includes Linux- and Windows-based software drivers.  These are re-usable by customers to reduce software development efforts and costs.  Additionally, IDT is offering a GUI-based software application environment to enable system configuration and optimization.

About IDT Serial-switching Division

The IDT serial-switching division, built in part by the acquisition of ZettaCom and its switch-fabric and traffic-manager solutions, the licensing of technology from Internet Machines Corporation, and the synergies with the company's internal experts, is focusing on developing Advanced Switching (AS) and PCI Express standards-based products.  The product portfolio consists of solutions that reaffirm the company’s commitment to meeting its customers’ applications requirements with the right standards-based products.  In addition to the recently announced family of PCI Express bridging and switching solutions, the IDT serial-switching division’s product portfolio consists of a family of switch-fabric and traffic-manager solutions that incorporate standard interfaces such as SPI-4.2 and CSIX, which lead to higher cost efficiencies for network equipment manufacturers and their customers. The high integration of these switch fabric and traffic managers allows for dramatically increased port densities and reduced power requirements, providing key operational benefits to service providers.
