Component maker VIA has just launched the world’s first USB 3.0 hub controller, the VIA VL810 SuperSpeed Hub Controller. The new USB 3.0 hub supports speeds up to 5Gb/s, which is ten times the speed of USB 2.0 ports, and it features one upstream and four downstream ports.
Enhanced Power Management
Along with power management features that include the ability for devices to communicate latency tolerance to the host and for links to enter progressively lower power states when link partners are idle, the VIA VL810 is unique in that it is the first USB hub controller to use advanced 80nm CMOS technology, further lowering the chip’s power usage.
The power management capabilities of the VIA VL810 are particularly noteworthy. By allowing devices to communicate their latency tolerance to the host, the hub can optimize power usage dynamically. This means that when devices are not actively transmitting data, the hub can reduce power consumption by entering lower power states. This feature is especially beneficial for battery-operated devices, as it can significantly extend battery life.
Moreover, the use of 80nm CMOS technology in the VIA VL810 not only reduces power consumption but also enhances the overall efficiency of the hub. This advanced technology allows for a more compact and cost-effective design, making it an attractive option for manufacturers looking to integrate USB 3.0 capabilities into their products.
Real-World Applications and Benefits
The introduction of the VIA VL810 SuperSpeed Hub Controller opens up a range of possibilities for both consumers and manufacturers. For consumers, the increased data transfer speeds mean that tasks such as transferring large files, backing up data, and streaming high-definition content can be done more quickly and efficiently. For example, transferring a 25GB high-definition movie file, which would take approximately 14 minutes with USB 2.0, can be completed in just over a minute with USB 3.0.
For manufacturers, the VIA VL810 offers a versatile solution for integrating USB 3.0 into a wide range of devices, from external hard drives and flash drives to docking stations and multimedia devices. The hub’s ability to support multiple downstream ports also means that users can connect several USB 3.0 devices simultaneously without experiencing a drop in performance.
Additionally, the VIA VL810’s backward compatibility with USB 2.0 and USB 1.1 devices ensures that users can continue to use their existing peripherals while taking advantage of the new hub’s enhanced capabilities. This seamless integration is crucial for a smooth transition to the new technology, making it easier for consumers to adopt USB 3.0 without having to replace all their current devices.
The VIA VL810 SuperSpeed Hub Controller represents a significant advancement in USB technology. Its high-speed data transfer capabilities, advanced power management features, and efficient design make it a valuable addition to the market. As more devices begin to adopt USB 3.0, the VIA VL810 is poised to play a crucial role in the evolution of data transfer technology.
