Broadcom PCI Interface IC, Part #: PEX8747-CA80FBC G | Integrated Circuit | DEX

Broadcom PCI Interface IC, Part #: PEX8747-CA80FBC G offers Multi-Host PCI Express switching capability enabling users to connect a host to its respective endpoints via scalable, high bandwidth, non-blocking interconnection to a variety of graphics applications. The PEX 8747 is optimized to support high-resolution graphics while supporting peer-to-peer traffic and multicast for maximum performance.

The PEX 8747 architecture supports packet cut-thru with a maximum latency of 100ns (x16 to x16). 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 PEX 8747 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.
