The VIA Lab’s VL811+ is an advanced USB 3.0 Hub controller featuring low power consumption and comprehensive USB Charging support without the need for external charger ICs. VL811+ employs an advanced CMOS process and supports USB power management, allowing for improved power-efficient operation. The custom in-house USB PHY gives VL811+ excellent signal integrity characteristics and improved backwards compatibility. VL811+ also features a flexible firmware architecture, providing a framework for custom functions as well as advanced feature support, in addition to in-field updates. The Via Lab’s VL811+ based hub devices work under Windows, Mac OS X, and various Linux kernels without additional drivers. Since USB 3.0 hubs do not require additional drivers, VL811+ is also compatible with non-x86 devices and platforms that support USB hub functions such as smart phones, tablets, and set-top boxes. It is well suited for all USB hub applications such as stand-alone USB hubs, Notebook/Ultrabook docking stations/port-replicators, desktop PC front panel, motherboard on-board hub, and USB hub compound devices. With well-planned pin-out and a high level of integration, VL811+ based devices enjoy easy layout and simplified BOM. Full sideband signal pins are available for showing power enable, over current, GPIO, and LED status control. The SPI interface supports external EEPROM/Flash ROM which can be updated over USB. VL811+ is available in a 4-port configuration utilizing the QFN 88L package (10x10x0.85 mm) which is pin-compatible with VL810/VL811. |
