FL1100LX – PCI Express to 1-Port USB 3.2 Gen1 Host Controller
The FL1100LX is single-chip PCI Express to USB 3.2 Gen1 host controller. It fully integrates an Extensible Host Controller Interface (xHCI) engine, a 5 Gbps USB 3.2 Gen1 transceiver, a PCI Express endpoint controller and a 1-lane 5Gbps PCI Express transceiver. FL1100LX implements the Universal Serial Bus 3.0 Specification Revision 1.0 and the Extensible Host Controller Interface (xHCI) Specification Revision 1.0, and complies with the PCI Express Rev 2.1 Specification at 5Gbps data rate, and is backward compatible to the PCI Local Bus Specification Revision 2.2. FL1100LX is compatible for operation with USB 2.0 and USB 1.1 devices.
Adding the FL1100LX into your PCI Express-based platform provides one high-performance USB port that can be used for any USB application, including video displays, high definition cameras, high-performance storage, or countless other devices.
The FL1100LX supports USB Debug Capability defined by the xHCI specification. Debug capability enables low-level system debug using a USB-to-USB connection between two computers, and is a requirement from Microsoft for those platforms.
