PEX 8547/8547S Lead Free 

PEX 8547: 48 Lane, 3 Port PCI Express Switch, 37.5 x 37.5mm² PBGA
PEX 8547S: 48 Lane, 3 Port PCI Express Switch, 27 x 27mm² PBGA

The ExpressLane™ PEX 8547/8547S device offers 48 PCI Express lanes, capable of configuring up to 3 flexible ports. The switch conforms to the PCI Express Base Specification, rev 1.1. This device enables users to add scalable high bandwidth, non-blocking interconnects to high-end graphics applications. The PEX 8547 is designed to support graphics or data aggregation while supporting peer-to-peer traffic for high-resolution graphics applications. The architecture supports packet cut-thru with the industry's lowest latency of 110ns (x16 to x16). This, combined with large packet memory (1024 byte maximum payload size) and non-blocking internal switch architecture, provide full line-rate on all ports for performance-hungry graphics applications. The PEX 8547 is offered in a 37.5 x 37.5mm² 736-ball PBGA package and PEX 8547S is offered in a 27 x 27mm² 736-ball PBGA package. The devices are available in lead-free packaging.
