PLX Introduces PEX 8111 PCI Express Bridge Chip

6/10/2004 - PLX Technology, Inc. (NASDAQ: PLXT), the leading supplier of standard I/O interconnect silicon to the communications, server, storage, embedded-control, and consumer industries, announced the PLX® PEX 8111, the industry’s smallest PCI ExpressTM bridge chip. Its rich array of features -- small 10mm by 10mm 161-ball plastic BGA package, support for forward and reverse bridging, and low power consumption (0.3 watts maximum) – enables board and system designers to easily migrate their legacy PCI products to the PCI Express architecture.

The PEX 8111 will sample in the second half of 2004 and be supported by PLX’s extensive Reference Development Kit (RDK) and Software Development Kit (SDK) design tools.

Small Form Factors in PCI Express
The PEX 8111 brings the power of PCI Express technology to applications with the most critical space limitations such as ExpressCardTM, MiniCardTM, Advanced Mezzanine CardTM (AMC) and Switched Mezzanine CardTM (XMC) products. These next-generation, small-form-factor designs for PCI Express are enhanced by the PEX 8111’s compact size.

CardBus product developers can take advantage of the PEX 8111’s forward bridging feature to migrate their cards to the ExpressCard platform. The 10mm x 10mm footprint of the PEX 8111 uses less than four percent of the 34mm x 75mm area of an ExpressCard/34 Module. For AMC applications, the PEX 8111 consumes less than one percent of the available PCB footprint. In addition to small-form-factor designs, the PEX 8111 also can be used in PCI Express-based motherboards, standard add-on cards, embedded systems and remote cable expansion cards to interface with legacy PCI devices.

“PCI Express is beginning to permeate all segments of system and board designs, including small-form-factor products with ever-tightening space and power requirements,” said Chris Youman, product marketing manager for PCI Express bridges at PLX. “What we’re enabling developers and manufacturers to do with the PEX 8111 is migrate existing designs to the powerful new PCI Express interconnect while solving some of their most pressing design needs -- all in a timely and economical way.”

Low Power
The 0.15 micron low-power CMOS design of the PEX 8111 enables a maximum power consumption of no more than 300 milliwatts. The strict thermal requirements of many small-form-factor designs for PCI Express demand silicon components that use less power. The PEX 8111 draws only about three percent of the proposed available power budget for typical next-generation PCI Express XMC modules. The PEX 8111 also supports advanced device and PCI Express link power management features.

Forward and Reverse Bridging
Product developers can take advantage of the PEX 8111’s forward and reverse bridging features to address the widest range of PCI Express applications possible. Reverse bridging allows the host processor to reside on the PCI bus, preserving designers legacy hardware and software architectures. They can utilize the latest complementary I/O silicon architectures and features, while bridging to widely entrenched legacy PCI endpoints, slots and backplanes.

Expanding Family of PCI Express Silicon
The PEX 8111 is the newest member of PLX’s recently announced line of PCI Express switches and bridges, announced in April 2004. The PEX line now includes the PEX 8111, the PEX 8114 PCI Express-to-PCI/PCI-X bridge, and PEX 8516 and PEX 8532 switching devices.

Among the PEX 8111’s key features are:

Availability, Pricing
The PLX PEX 8111 will sample in the second half of 2004 and is priced at under $15 in volume. For more information on PEX 8111, contact PLX Technology at 800.759.3735 or go to
