ASM2464PDX Integrated Circuit Chip USB4 Device Controller with 40G USB4/Thunderbolt PCIe Gen4 x4 and NVMe SSD Data Clone

ASM2464 is a new generation USB4/Thunderbolt to PCIe/NVMe Accessory controller based on ASMedia in-house designed PHYs. USB4/Thunderbolt technology enables PCIe and USB protocols encapsulated into the USB4/Thunderbolt fabric and tunneled across USB4/Thunderbolt domains.
When connecting to a USB4/Thunderbolt PCIe Tunneled host, ASM2464 can support various types of general PCIe devices (including AI controllers, external graphics cards, PCIe network controllers, AHCI RAID controllers, xHCI controllers, PCIe packet switches, etc.) in addition to NVMe SSD (such as M.2 NVMe SSD, CFexpress, U.2, U.3, etc.).
The ASM2464 USB connection provides data rates at USB4/Thunderbolt 20Gbps x2 and is compatible with existing legacy USB 3.2 interfaces, as well as Thunderbolt 3. The downstream port link is upgraded to PCIe Gen4 x4, with configurable PCIe lanes (PCIe 4 x1, 2 x2, 1 x2+2 x1, and 4 x1) to support up to four PCIe devices. ASM2464 also supports 1-to-1/1-to-3 data clone function for copying full SSD data from source to destination drives.
