PL2701 Super-Speed USB Host to Host Bridge Controller (ULinQ)

PL2701 is a single-chip SuperSpeed USB (USB 3.0) host-to-host bridge controller designed for connecting two computers or devices with USB hosts running Android™, Linux, iOS, Mac OS, or Windows® operating system. SuperSpeed USB (USB 3.0) reaches data transfer rates up to 5Gbps, offering 10x faster performance over Hi-Speed USB (USB 2.0) and is backward compatible with USB 2.0 hosts, devices, and hubs. PL2701 uses a “Hybrid Multi-Class” channel allowing two USB hosts to share resources, such as a keyboard or mouse, network, mass storage devices, displays, and multimedia. PL2701 default supports Remote Network Driver Interface specification (RNDIS), WinUSB, HID, Audio, and Mass Storage USB device classes. PL2701 also provides a flexible endpoint assignment mechanism that allows many applications to be implemented through this high performance host-to-host bridge controller.
