This expansion board is designed based on ASMedia's ASM2464PD specifications and serves primarily to convert USB4 or Thunderbolt 3/4 interfaces to standard PCIe/NVMe connections. ASM2464PD represents a new generation of USB4®/Thunderbolt to PCIe/NVMe accessory controllers, incorporating ASMedia's proprietary PHY designs. The USB4/Thunderbolt technology facilitates the encapsulation of PCIe and USB protocols within the USB4/Thunderbolt framework, allowing for the tunneling of these protocols across USB4/Thunderbolt domains. ASM2464PD can be applied to various types of storage devices, including portable SSDs, SSD enclosures, and other PCIe-based storage solutions that enhance storage capacity while ensuring high-speed data transfer. The USB connection specified in ASM2464PD is capable of achieving a data transfer rate of 20 Gbps, utilizing USB4/Thunderbolt technology in a dual configuration. It is also compatible with existing legacy USB 3.2 interfaces, in addition to supporting Thunderbolt 3. Furthermore, the downstream port link of ASM2464PD has been enhanced to PCIe Gen4 x4, facilitating compatibility with various NVM Express-based M.2 devices. Key Features 40Gbps Speed: This expansion board converts your M.2 NVMe SSD into a compact and portable mobile hard drive. It is equipped with a USB4.0 Type-C output interface, supporting a maximum data transmission speed of up to 40Gbps. Featuring the latest ASM2464 chip, it is compatible with Thunderbolt 3 and 4 and supports both PCIe and USB dual tunnels. Multiple Transmission Protocols: The board is compatible with multiple transmission protocols and interfaces, ensuring broad adaptability. It supports USB 4 / Thunderbolt 3 / Thunderbolt 4 with a maximum transmission rate of 40Gbps.
