VL812 USB 3.0 Hub Controller (B2)
VL812 System Overview
VIA Lab’s VL812 is an advanced 4-port USB 3.0 Hub controller featuring fully-integrated voltage
regulators, low power consumption, and comprehensive USB Charging support. The integrated 5V DC-DC
switching regulator enables VL812 to be powered directly from 5V USB VBus, reducing BOM cost while
offering high power efficiency. The custom in-house USB PHY supports USB power management and
gives VL812 excellent signal integrity characteristics and improved backwards compatibility. VL812 also
features a flexible firmware architecture, providing a framework for custom functions in addition to
in-field updates.
VL812 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 pinout and a high level of integration, VL812 based devices enjoy easy layout and
simplified BOM. 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. VL812 is available in QFN 76L green package (9x9x0.85 mm) to fit small form-factor designs.
