PLX, Rambus Exhibit PCI Express Switching at Intel Developer Forum Con

    Business Editors/High-Tech Editors
    Intel Developer Forum

    TAIPEI, Taiwan & BEIJING--(BUSINESS WIRE)--April 11, 2005--PLX Technology, Inc. (Nasdaq:PLXT) and Rambus Inc. (Nasdaq:RMBS) will jointly exhibit at the Intel Developer Forum (IDF) in both Taiwan and China this week a high-performance PLX(R) PCI Express(TM) (PCIe) solution that incorporates Rambus(R) technology. The PLX PCIe exhibit is based on the PLX(R) ExpressLane(TM) PEX 8532, a 32-lane PCIe switch incorporating the Rambus RaSer(TM) serial/deserializer (serdes) technology.
    PLX is the leading supplier of standard I/O interconnect silicon to the communications, server, storage, embedded-control, and consumer industries. Rambus is one of the world's premier technology licensing companies specializing in high-speed chip interfaces. The PEX 8532-based board is part of the PLX PEX 8532 RKD rapid development kit, which PLX is announcing this week.
    The PEX 8532 is the industry's only 32-lane PCIe switching device with eight flexible ports, two virtual channels and non-transparent bridging. The device's flexible port widths allow any port to be configured as either upstream or downstream through hardware strapping, software configuration or an optional EEPROM. Non-transparent bridging on the PEX 8532 enables any one port to isolate two host or memory domains, enabling use of the PCIe technology in intelligent I/O modules, dual-host and multi-host architectures.
    PLX has licensed Rambus's RaSer technology for the ExpressLane family to enable the 2.5-gigabits-per-second, point-to-point, serial interface connections required for PCIe-based systems.
    "Demonstrating the PLX board in our booths at IDF Taiwan and Beijing will allow customers to get a first-hand look at a best-in-class PCI Express technology implementation," said Jean-Marc Patenaude, director of marketing at Rambus. "We are very pleased to work with PLX on bringing this solution to market."
