ASM4242 | USB4 Host Controller 40G
Winning Reason
1. After receiving USB-IF certification in early 2024, ASMedia's ASM4242 USB4 host controller chip now also has Thunderbolt 4 certification. It is one of the world's few standalone host controller chips with dual certification for USB4 and Thunderbolt 4, providing a more comprehensive high-speed transmission solution and creating a superior end-user experience.
2. The chip supports high-speed connections between two hosts, enabling large data transfers, shared displays, or the use of PCIe devices.
3. Through a USB4 external PCIe interface, it allows the host to connect an external GPU, enhancing system graphics and AI computing capabilities.
Product Feature
The ASM4242 is ASMedia’s first generation of USB4 host controller. It features upstream ports with 4-lane PCI Express 4.0 (PCIe Gen 4) and dual 4-lane DisplayPort sink ports, and downstream facing ports with dual USB4 ports.
