10Gbit USB 3.1 second generation hub controller eyes USB-C

By Nick Flaherty www.flaherty.co.uk

VIA Labs in Taiwan has developed the world’s first USB-IF certified USB 3.1 Gen 2 Hub controller with an eye on future USB-C systems.

The VL820 USB 3.1 Gen 2 Hub Controller has achieved SuperSpeed USB 10Gbit/s certification from the USB Implementers Forum (USB-IF), filling out the complete range of support.

The VL820 supports one upstream port and four downstream ports, each capable of supporting SuperSpeed USB 10Gbps devices, while providing backward compatibility for previous generation USB devices. The support for USB-C is an an optionally configurable USB Billboard Device for Alternate Mode applications such as Thunderbolt 3 peripherals or DisplayPort over USB-C multi-function dongles.

“The VIA Labs VL820 has been over two years in the making, and our top priority during the development process was ensuring excellent interoperability,” said Jay Tseng, Director, VIA Labs Inc. “Throughout this process, we co-tested with every major USB 3.1 Gen 2 Host provider and various device manufacturers and test tool companies in a collaborative effort to reach this goal.”

"Certified USB products from companies including VIA Labs lay the foundation for successful market adoption and interoperability,” said Jeff Ravencraft, USB-IF President and COO. “USB-IF is pleased that VIA Labs has achieved certification of its USB 3.1 Gen 2 Hub controller, representing the final piece to ensure a fully functional SuperSpeed USB 10Gbps ecosystem guided by the USB-IF compliance program.”

The controller has two configurations: VL820-Q7 is the standard configuration in a QFN-76 9x9mm package. VL820-Q8 is optimised for USB-C, integrating muxes for the upstream port and two downstream ports in a manufacturing-friendly QFN-88 10x10mm package.

The VIA Labs VL820 Hub controller is available now and shipping in quantity. It is already seeing strong adoption in USB-C peripherals, docking stations, monitors, gaming devices, and other product categories., says VIA, with end products will be available as early as Christmas.
