The first multi-port USB4 hub controller with USB-C and fast charging. Doubles speed to 40Gbps supports multiple displays and enables data transfer.
Realtek Semiconductor Corp. has introduced the RTS5490, the world’s first multi-port USB4 hub controller with integrated USB Type-C/PD functionality. It has passed USB-IF full certification (TID: 11930).
The RTS5490 increases bandwidth from USB 3.2’s 20Gbps to USB4’s 40Gbps and supports USB 3.2, USB-C, USB PD, PCIe, and DisplayPort. It remains backwards compatible with USB 3.2 and USB 2.0 devices. Users can expand their computer’s ports with a single USB-C cable, enabling high-speed data transfer, multi-display support, and 240W fast charging.
This USB4 solution ensures flexibility and compatibility with Thunderbolt 3 devices. Key features include:
- One upstream USB4 port, two downstream USB4 ports
- Two USB 3.2 Gen 2×2 downstream ports
- DisplayPort 2.1 with one input and one output port
The RTS5490 supports AI acceleration via USB4/Thunderbolt external GPUs and high-speed data sharing using inter-domain transfer. It integrates a 32-bit processor, a USB 2.0/3.2 hub, a DisplayPort controller, a PCIe switch, and a USB 3.2 host controller, making it one of the most competitive USB4 hub controllers available.
“Our RTS5490 is the only fully USB-IF Certified USB4 hub product on the market to integrate USB Type-C and USB PD 3.2 controllers. This significantly simplifies the design complexity in products like PCs, docks, and displays, greatly shortening the product development cycle,” said Yee-Wei Huang, Realtek’s Vice President and Spokesman. “We will continue to innovate and drive continuous progress and development of data transfer technologies.”
