Description
VIA Lab’s VL822-Q8 is USB 3.1 Gen 2 Hub Controller and it features highly integrated, application specific design. VL822 features 1x upstream port and 4x/2x downstream ports, all of which support 10Gbps USB 3.1 Gen 2 operation. The downstream ports can support any combination of SuperSpeed Plus (10Gbps), SuperSpeed (5Gbps), High Speed (480Mbps), Full Speed (12Mbps), and Low Speed (1.5Mbps) devices. VL822’s integrated USB 2.0 hub features Multiple Transaction Translators, providing increased bandwidth and performance when multiple Full Speed devices are simultaneously used.
VL822 comes in three variants: VL822-Q8 utilizes the QFN88 10x10x0.85 mm package while the VL822-Q7 utilizes the smaller QFN76 9x9x0.85mm package and VL822-Q5 utilizes the smaller QFN56 7x7x0.85mm package for two port configure. The larger QFN88 variant features integrated 10Gbps Muxes for the Upstream Facing Port and two Downstream Facings Ports whereas the smaller QFN76/QFN56 variant does not. The integrated 10Gbps Muxes are ideal for Data-Only USB-C applications that would otherwise require an external Mux, with the advantage of potential board area savings and improved signal integrity. If additional USB-C Ports are need, separate CC Logic and Mux solutions.
VL822 features an optionally configurable USB Billboard Device when used in USB-PD Alternate Mode applications, and an optionally configurable USB HID endpoint to support Media Control Buttons such as Play/Pause, Volume Up/Down, etc.
