PEX 8648
PCIe Gen2, 5.0GT/s 48-lane, 12-port PCIe Switch
The ExpressLaneTM PEX 8648 device offers PCI Express switching capability enabling users to add scalable high bandwidth, non-blocking interconnection to a wide variety of applications including servers, storage systems, and communications platforms. The PEX 8648 is well suited for fan-out, aggregation, and peer-to-peer applications. High Performance & Low Packet Latency The PEX 8648 architecture supports packet cut-thru with a maximum latency of 140ns (x16 to x16). This, combined with large packet memory 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. Data Integrity The PEX 8648 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 as packets pass through the switch. Flexible Register & Port Configuration The PEX 8648’s 12 ports can be configured to lane widths of x1, x2, x4,……
