VL210 - Super Speed USB 3.0 Hub Controller

Description


 
The VIA Lab’s VL210 is a 4th generation advanced USB 3.0 Hub controller featuring a simplified port configuration. VL210 features four downstream ports: a single USB 3.0 and three USB 2.0 ports, each with comprehensive USB Charging without the need for external charger ICs. The VL210 employs an advanced CMOS process for greatly reduced power consumption and fully supports USB power management and low-power states. The custom in-house USB PHY gives VL210 excellent signal integrity characteristics under a variety of channel conditions and now supports improved USB EMI profile support including the new 2.4GHz Radio Friendly mode. VL210 features a highly 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 VL210 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, VL210 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, 2-in-1 convertible Tablets, and USB hub compound devices.

With well-planned pin-out and a high level of integration, VL210 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.
