Broadcom PCI Interface IC, Part #: PEX8718-AB80BI G | Integrated Circuit | DEX

Broadcom PCI Interface IC, Part #: PEX8718-AB80BI G 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 PEX8718 is well suited for fan-out, aggregation, and peer-to-peer applications.

The PEX8718 employs an enhanced architecture, which allows users to configure the device in legacy single-host mode or multi-host mode with up to two host ports by using NT capability. This powerful architectural enhancement enables users to build PCIe based systems to support highavailability, failover, redundant and clustered systems.

The PEX8718 architecture supports packet cut-thru with a maximum latency of 154ns (x8 to x8). 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 PEX8718 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.
