PEX8764-AB80BI G

The Express Lane7''1 PEX8764 device offers Multi-Host PCI Express switching capability enabling users to connect multiple hosts to their respective endpoints via scalable, high bandwidth, non-blocking interconnection to a wide variety of applications including servers, storage systems, and communications platforms. The PEX8764 is well suited for fan-out. aggregation, and peer-to-peer applications. The PEX8764 employs and enhanced architecture, which allows users to configure the device in legacy single-host mode or multi-host mode with up to four host ports capable of 1 + 1 (one active & one backup) or N+1 (N active & one backup) host failover. This powerful architectural enhancement enables users to build PCIe based systems to support high-availability, failover, redundant and clustered systems. The PEX8764 architecture supports packet cut-thru with a maximum latency of 150ns (\16 to xl6). This, combined with large packet memory, flexible common buffer/FC credit pool and non-blocking internal switch architecture, provides full line rate on all ports for performance-hungry applications such as servers and switch fabrics. The low latency enables applications to achieve high throughput and performance. In addition to low' latency, the device supports a packet payload size of up to 2048 bytes, enabling the user to achieve even higher throughput. The PEX8764 provides end-to-end CRC (ECRC) protection and Poison bit support to enable designs that require end-to-end data integrity. PLX also supports data path parity and memory (RAM) error correction circuitry throughout the internal data paths as packets pass through the switch.
