Description
VIA Lab’s VL817 is a modern USB 3.1 Gen 1 Hub Controller, featuring an optimized cost-structure and full compliance with USB 3.1 Gen 1 specification including ECNs and Compliance Testing Updates through Jan 2017. VL817 is offered in both 2-port and 4-port configurations, and features integrated voltage regulators, new lower-power design, and comprehensive USB Charging support. VL817 supports any combination of SuperSpeed (5Gbps), High Speed (480Mbps), Full Speed (12Mbps), and Low Speed (1.5Mbps) devices, and the integrated USB 2.0 hub’s Multiple Transaction Translators feature provides increased performance when multiple Full Speed devices are simultaneously used. The integrated 5V DC-DC switching regulator enables VL817 to be powered directly from 5V USB VBus, reducing BOM cost while offering high power efficiency.
VL817 features flexible firmware architecture, providing a framework for custom functions in addition to in-field updates. Various parameters including Tx equalization setting and GPIO behavior are changeable via firmware, including the optionally configurable USB Charging Controller for charging various devices such as smartphones and tablets.
VL817-based hub devices work under Windows, Mac OS X, and various Linux kernels without additional drivers.
