ASM2464PDX
USB4 Device
ASM2464PDX, 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 to be encapsulated into the USB4/Thunderbolt fabric and tunneled across USB4/Thunderbolt domains. ASM2464PDX can be implemented with various types of general PCIe devices in addition to NVMe SSD. The ASM2464PDX 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 ASM2464PDX is also upgraded to PCIe Gen4 x4. The downstream PCIe lanes are configurable to support up to four PCIe devices. ASM2464PDX integrates USB4/Thunderbolt Gen3 x2, and PCI Express Gen4 with VDD, VCCL, VCCH voltage power source. A USB Type-C CC logic circuit and BMC PHY are integrated for supporting cable orientation, flipping, and PD Sink mode with the capability to communicate via PD protocols including USB4/TBT3 Discovery and Entry with host. A discrete PD controller can be supported through I2C to achieve advanced USB PD functions. ASM2464PDX is driven by local 25MHz crystal in a compact RoHS Green compact package with the support of multiple GPIO pins for customization.
