PLX Technology introduced SuperSpeed USB (USB 3.0) general-purpose peripheral controllers that bridge USB 3.0 to PCI Express (PCIe) 2.0, thus matching the high-performance 5 Gbps bus speed . This controller family targets applications such as tablets, mobile PCs, printers, projectors, embedded systems, multiple-input and multiple-output (MIMO) WiFi adapters, graphics/video adapters, TV Tuners, and the new Thunderbolt adapters. The company’s complementary USB software suite helps add a USB 3.0 peripheral port to PCIe-based systems, as well as convert PCIe endpoints to a USB 3.0 product. Existing designs with the PLX NET2282x Hi-Speed USB 2.0 controller can upgrade to the new USB338x product family with minimal or no software changes. Driver stacks are already available for operating system-independent applications, as well as for common operating systems. The new PLX USB3382 features two PCIe Gen2 x1 ports with flexible port configurations for different needs of PCIe buses, while the USB3380 is designed with one PCIe Gen2 x1port, and both feature high-efficiency power management. The USB338x family is designed to meet the power constraints for battery-powered and bus-powered applications. Both solutions support PLX USB Duet® technology, which focuses on the tablet and mobile-PC market and provides fast PC-to-PC interconnect for data synchronization and sharing.
