VIA Labs, a subsidiary of VIA, released the world’s first USB4 Endpoint device controller, VL830, which is fully compatible with USB 4, USB 3.2, USB 2.0, and DP 1.4 standard specifications, and supports full-speed USB 4 and DisplayPort 1.4. DisplayPort 1.4 has a maximum transmission rate of 32.4 Gbps and is compatible with DisplayPort Alt Mode.

The USB 4 standard specification is regarded by the industry as a major reform of the USB port. It has been released for two years. Under the new standard specification, multiple data and display protocols can share a high-speed link channel with a transmission rate of up to 40 Gbps. Under Thunderbolt 4 or USB 4, VL830 can provide full performance operation of USB and DisplayPort transmission at the same time, and is backward compatible with USB Type-C DP alternative mode (DisplayPort Alt Mode), not only can support notebook computers in this mode, but also support tablet or smartphone.

VL830 uses a 10 x 10 mm package size (FCCSP), integrates a USB 3.2 Hub, can output four USB 3.2, one USB 2.0, and one DisplayPort 1.4, which can make full use of the full bandwidth of 40 Gbps. Compared with the DP alternative mode of USB Type-C, VL830 can support a single 8K@60Hz high dynamic range (HDR) display and multiple USB 3.2 Gen2 devices at the same time. If paired with DisplayPort multi-stream transmission (MST), VL830 can support multiple 4K or high refresh rate displays, and USB high-speed data transmission at the same time.

VIA Labs stated that VL830 represents the technology and experience of the VIA Labs R&D team in the development of USB Type-C, USB PD, and USB 3.2. From the product launch to the contribution of participating in standard development, it is in the leading position in the industry. VL830 provides a brand-new and price-competitive product solution. VL830 will start shipping in the fourth quarter of this year.
