ASM2464PD Integrated Circuit Chip 40G USB4/Thunderbolt To PCIe Gen4 x4 NVMe Bridge Controller

ASM2464PD Integrated Circuit Chip 40G USB4/Thunderbolt To PCIe Gen4 x4 NVMe Bridge Controller​

Product Description

ASM2464 is a new generation of 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. ASM2464 can be a solution to implement in various types of storage devices such as portable SSD, SSD enclosure, and any other PCIe based storage products expanding storage capacity with high-speed data transfers.

ASM2464 USB connection is able to provide data rate at a speed of USB4/Thunderbolt 20Gbps x2 and is compatible with existing legacy USB 3.2 interfaces, as well as Thunderbolt 3. In addition, the downstream port link of ASM2464 is also upgraded to PCIe Gen4 x4 to support various NVM Express based M.2, CFexpress, and U.2 form factors.

ASM2464 integrates USB4/Thunderbolt Gen3 x2, and PCI Express Gen4 with VDD, VCCL, VCCH voltage power sources. Integrated USB Type-C CC logic circuit and BMC PHY support cable orientation, flipping, and PD Sink mode with the capability to communicate via PD protocols including USB4/TBT3 Discovery and Entry with host. ASM2464 driven by local 25MHz crystal in a compact RoHS Green package also supports multiple GPIO pins for customization.
