Corporate networks today are providing greater bandwidth than ever before with LANs routinely allowing 100 Mbps network connections. Current high speed network printers with multifunction/inputs often are designed with the ubiquitous internal PCI interconnect for its low cost, standardized interfaces, and availability. The PEX 8508 is an economical 5-port/8-lane PCI Express switch with a host of capabilities that match printer engine controller designs. The switch has extensive throughput with up to eight lanes available, a wide variety of lane-to-port configuration options including a one x4—lane and 4 x—1 lane setting, and has a complete line of power management options.
