Broadcom PCI Interface IC, Part #: PEX8615-BA50BC G | Integrated Circuit | DEX

Broadcom PCI Interface IC, part PEX8615-BA50BC G offers PCI Express switching capability enabling users to add scalable high bandwidth non-blocking interconnection to a wide variety of applications including control planes, communication platforms, servers, storage systems and embedded systems. The PEX 8615 is well suited for fan-out, aggregation, peer-to-peer, and intelligent I/O module applications. 

The PEX 8615 architecture supports packet cut-thru with a maximum latency of 140ns. This, combined with large packet memory and non-blocking internal switch architecture, provides full line rate on all ports for low-latency applications such as communications and servers. The low latency enables applications to achieve high throughput and performance. In addition to low latency, the device supports a max payload size of 2048 bytes, enabling the user to achieve even higher throughout.

The PEX 8615 provides a versatile and powerful DMA engine built in to the device which can be used as a stand alone DMA engine. The DMA engine removes the burden resulting from having to move data between devices away from the processor. This allows the processor to perform computational tasks instead. The four DMA channels can support high data rate transfers between IO devices connected to any of the available ports in the PEX8615. Additionally, the DMA engine in the PEX 8615 can be used to complement the DMA engine in the processor by providing additional DMA channels for higher performance.

The PEX 8615 provides end-to-end CRC protection (ECRC) and Poison bit support to enable designs that require guaranteed error-free packets. PLX also supports data path parity and memory (RAM) error correction as packets pass through the switch.
