描述 Description

ASM1142 is an ASMedia first Universal Serial Bus 3.1 host controller, compliant with Intel eXtensible Hot Controller Interface specification revision 1.1, bridging PCI Express interface to two ports of USB3.1, up to 10Gbps high speed bandwidth, backward compatible with legacy USB function and devices. It can configure PCI Express as Gen2x2 or Gen3x1, compliant with USB Attach SCSI Protocol revision 1.0, supporting the functions of debugport.

ASM1142 integrates ASMedia self-designed PCI Express/USB 3.1 PHY, and it also integrates two internal regulators to supply normal core power and suspend core power, supporting the driver on Windows 7, Windows 8.0, Windows 8.1 and various Linux Kernels. The application of ASM1142 includes Motherboard, Desktop PC, Notebooks, Workstations, Servers, Add-in card, PCI Express based embedded platform.
