Announcement Demonstrates Company’s Commitment to Advanced Switching Interconnect and Standards-based Switching Applications
June 7, 2005

Santa Clara, Calif., June 7, 2005 — To further the development of Advanced Switching Interconnect (ASI)-based systems, IDT(Integrated Device Technology, Inc.; NASDAQ:  IDTI) announced today an FPGA-based prototype technology that will demonstrate the interworking of the common switch interface (CSIX) datapath protocol into ASI.  This prototype technology, which uses the Generic Data Transport protocol interface, or PI-2, specified by the ASI Special Interest Group (SIG), will enable customers to develop early prototype systems based on ASI with a seamless migration to production platforms.  Applications targeted are up to 10 Gbits per second (Gbps) line-card subsystems in full carrier-class communications platforms, such as multi-service access routers and broadband remote access servers.


As part of the IDT strategy for supporting standards-based switching solutions, IDT may leverage this technology as the basis for subsequent offerings related to the connectivity and interworking of various endpoint devices, including NPUs, µP, DSPs and CPUs.   


“Advanced Switching continues to gain acceptance in communications and computing applications,” said Mario Montana, general manager for the IDT serial-switching division.  “We view this effort as one of the key components in the enablement of standards-based modular communications platforms for the carrier market.  We are proud to take a leadership role in driving datapath interworking for ASI and, thereby, assisting our customers in the design of their ASI-based solutions.”


“2006 continues to be a major inflection point for the industry transition to Modular Communications Platform elements, and we expect to see significant adoption of ASI as the standardized fabric interconnect,” said Rajeev Kumar, president of the Advanced Switching Interconnect Special Interest Group (ASI SIG) and ASI Initiatives manager at Intel Corporation.  “An important milestone has been reached in 2005 with a number of leading companies announcing products and architectures based on ASI technology.  IDT has been among those companies forwarding ASI by using its switching and systems expertise to deliver a critical component for the ecosystem, which will enable existing processor connectivity into an ASI-based fabric.             

The IDT prototype technology will be delivered in a mezzanine card for use in ATCA-based carrier boards or in an FPGA bit stream format for customer-specific sub-systems designs.  For additional information on the IDT prototype technology, please contact
