PLX Technology Samples 16-lane ExpressLane PEX 8516 PCI Express Switch

12/9/2004 - PLX Technology, Inc. (NASDAQ: PLXT), the leading supplier of standard input/output (I/O) interconnect silicon to the communications, server, storage, embedded control, and consumer industries, announced sampling of another member of the PLX® ExpressLaneTM family of PCI ExpressTM (PCIe) switching and bridging devices. PLX has begun sampling the 16-lane ExpressLane PEX 8516 switch to its early customers.

System and board designers now can order from PLX samples of the PEX 8516, which is available in a 27x27mm, 312-pin BGA package. Additionally, designers can order a PLX Rapid Development Kit (RDK), enabling them to evaluate PEX 8516 features, streamline product development and bring their designs to market faster.

Interoperability with Wide Range of PCI Express Systems, Boards
The PEX 8516 switching device is the industry’s only 16-lane PCIe switch with four flexible ports, two virtual channels, and non-transparent bridging. The device provides flexible port widths, allowing any port to be configured as either upstream or downstream through hardware strapping, software configuration or an optional EEPROM. The PEX 8516 switch provides a standard Hot Plug controller on each port to enable field upgrades. Furthermore, it provides optional end-to-end cyclic redundancy checks (ECRC) to support the applications that require guaranteed data integrity while it moves from source to destination. In addition to the basic error reporting, the PEX 8516 supports advanced error reporting, thus easing system development, debug and optimization.

Family of PCIe Switches Now Sampling
The PEX 8516 is the second of PLX’s PCIe switches to commence sampling; the PEX 8532, a 32-lane switch, began sampling in September of this year. Both the PEX 8516 and PEX 8532 enable quality of service through the mapping of eight traffic classes on two fully featured virtual channels, with arbitration support for each port for applications such as server, storage, multimedia and communication. Additionally, they are the only pair of PCIe devices that offer a non-transparent bridging function that isolates two hosts or a single host from a processor on an intelligent I/O module. Furthermore, the devices’ non-transparency feature allows the use of the PCIe switching technology in switch-fabric architecture.

The rich features and flexibility of the PEX 8516 switch enable designers of new applications to take advantage of PCIe technology’s efficiencies and advanced features. System and board designs based on the PEX 8516 can utilize the high bandwidth of PCIe technology in legacy PCI applications, while using existing software developed for the PCI interconnect. The PEX 8516 switch can be used in fan-out, peer-to-peer, aggregation, multi-host, intelligent-I/O, and high-availability applications.

“PLX is delivering innovative solutions to meet the needs of a broad range of applications by sampling a second fully functional PCI Express switching device within a span of just two months, marking a significant achievement in PCI Express component availability,” said Akber Kazmi, PLX product marketing manager. “As a major contributor to both the PCI Express specification and the ecosystem for this technology, PLX is again distinguishing itself among PCIe component suppliers and affirming its leadership position by sampling yet another PCI Express switch with unmatched flexibility and features.”

The PLX ExpressLane family of products consists of PCIe switches and PCI/PCI-X-to-PCIe bridges.
