PEX 8509
8 Lane, 8 Port PCI Express Switch, 15 x 15mm PBGA
The ExpressLane™ PEX 8509 8-lane, 8-port switch product offers PCI Express switching capability conforming to the PCI Express Specification r1.1. This device with an equal number of lanes and ports can be used in a wide variety of applications including control planes in the communications and networking markets, embedded systems, multi-function printers, network interface adapters, medical imaging systems, industrial-control systems and AMC cards. The PEX 8509 architecture supports packet cut-thru with the industry's lowest latency of 118ns (x4 to x1). This, combined with large packet memory (1024 byte maximum payload size) and non-blocking internal switch architecture, provide full line-rate on all ports. This switch is hardware configurable and software programmable, allowing users to tailor their port configurations and quality-of-service system needs to suit their application requirements. The PEX 8509 is offered in the industry's smallest package of 15 x 15mm 196-ball PBGA. The device is available in leaded and lead-free packaging.
