Analogix Introduces Its VirtualLink Reference Design for High-Performance Gaming Notebooks

The Analogix VirtualLink Rd Brings VR Support to Gaming Laptops That Will Connect to Future VR HMDs with a Single Cable

Analogix Semiconductor, Inc. announced the availability of its VirtualLink Reference Design which enables VirtualLink directly on the motherboard of high-performance gaming notebooks, allowing them to support virtual reality (VR) over the USB-C™ connector. External accessories can also leverage the reference design to interface legacy graphics processing units (GPUs) to future VirtualLink-enabled VR head-mounted displays.

Analogix #VirtualLink™ Reference Design brings #VR support to high-performance gaming laptops connecting to VR #HMDs over the #USBTypeC connector with a single cable.

Introduced by a consortium led by NVIDIA, Oculus, Valve, AMD, and Microsoft, the VirtualLink Alternate Mode of USB Type-C™ was designed to deliver the power, display, and data required to power VR headsets through a single USB Type-C connector, eliminating the need for multiple cables. It expands on the USB Type-C connector’s capabilities to deliver high-definition video at high frame rates, high-speed 10Gpbs USB-C data for camera and sensor communication back to the VR source, and up to 27W power delivery to the VR headset.
