The company, which has a design centre in Dublin, Ireland, developed chips for the new VirtualLink open standard that is backed by NVIDIA, AMD, Oculus, Valve, and Microsoft. This is a USB Type-C alternate mode that will be able to supply all of the necessary power, video information, and data over a single USB Type-C cable and connector.

The DreamWeVR chips are already being embedded in USB Type-C cables allowing the copper conductors to be reduced, allowing a cable as small in diameter and weight as a standard ear-bud cable while still transferring ultra-high-speed video and data.

“We are extremely pleased that our products already meet the requirements of the new interface standard,” said Raouf Halim, CEO of Spectra7 and former CEO of Conexant spinoff Mindspeed Technologies. “We believe our technology will continue to be the preferred solution for VR products utilizing the new interface standard and we look forward to working with market-leading manufacturers seeking to incorporate our chips into cables supporting the new standard.”

The chips are purpose-built for AV, VR, and MR cable applications and can be embedded in wearable cables. The VR8300 DisplayPort HBR3 Embedded Cable Processor supports DisplayPort bandwidth of up to 32.4Gbit/s at 5K resolution for 15 million pixel cinema-grade video. The VR8200 DisplayPort HBR2 Embedded Cable Processor provides bandwidth of up to 21.6Gbit/s at 4K resolution while the VR8051 USB 3.2 Gen 2 Embedded Cable Processor provides 10Gbit/s of sensor/camera data for positional tracking and gesture recognition. The VR8050 supports 5Gbit/s for USB 3.2 Gen 1 links for sensor/camera data for positional tracking, and gesture recognition.
