With Realtek's years of technology and experience in USB and DisplayPort, the RTS5490 USB4 hub solution realizes the full USB4 function, including USB4, USB 3.2, Thunderbolt 3, DisplayPort 2.1, Type-C and PD 3.1 applications are integrated into a single chip, without the need for additional controllers, allowing developers to complete product development more quickly and easily while reducing the development cost of new products. The built-in ARM processor allows developers to obtain more flexible customized designs and shape product differentiation. To meet the security requirements of today's digital products, Realtek has added security algorithm/digital signature algorithm hardware functions to this product, so that it can always protect internal programs from malicious attacks during high-speed computing.
In addition, Realtek's high-bandwidth USB4 hub solution can expand desktop computers, notebooks, tablets, mobile phones and game consoles with multiple high-speed transmission ports and high-definition image output ports through a single USB C cable, reducing desktop clutter and increasing convenience. What’s more special is that the USB Type-C R2.2 and USB PD R3.1 controllers are integrated, which can not only charge and power the downstream devices, but also reve-rse charge the upstream host, with a maximum output of 240W. This solution is particularly suitable for dock and dongle applications such as various computer peripherals, gaming peripherals, and handheld device peripherals.
The Purplelec TU001 USB4 hub uses the Realtek RTS5490 chip, which includes 1 USB4 upstream port, 2 USB4 downstream ports, with a data transmission speed of 40Gbps, 1 power interface, supports PD3.0 fast charging protocol, supports 20V/7.5A, 2 USB-C ports, with a transmission speed of 20Gbps, backward compatible with USB3.0/USB2.0, 1 DP1.4 port, and supports 8K60Hz.
