标准范围

IEC 62680-3-1:2017定义了最新一代USB行业标准USB 3.1。本规范描述了协议定义、事务类型、总线管理以及设计和构建符合本规范的系统和外围设备所需的编程接口。USB 3.1主要是对SuperSpeed USB 3.0的性能增强，为固态硬盘和高清显示器等设备提供了两倍以上的带宽。它将增强型超高速称为适用于USB 3.0和USB 3.1总线操作的功能或要求的集合。此外，如果USB 3.0对SuperSpeed功能或要求的定义存在特定差异，则这些差异将被唯一标识为SuperSpeedPlus（或SSP）功能或要求——通常，“SuperSpeed”指的是5 Gbps操作，“SuperSpeedPPlus”指的则是10 Gbps操作。

IEC 62680-3-1:2017 defines the latest generation USB industry standard, USB 3.1. The specification describes the protocol definition, types of transactions, bus management, and the programming interface required to design and build systems and peripherals that are compliant with this specification. USB 3.1 is primarily a performance enhancement to SuperSpeed USB 3.0 resulting in providing more than double the bandwidth for devices such as Solid State Drives and High Definition displays. It refers to Enhanced SuperSpeed as a collection of features or requirements that apply to both USB 3.0 and USB 3.1 bus operation. Additionally, where specific differences exist with regard to the USB 3.0 definition of SuperSpeed features or requirements, those differences will be uniquely identified as SuperSpeedPlus (or SSP) features or requirements – generally, “SuperSpeed” is in reference to 5 Gbps operation and “SuperSpeedPlus” is in reference to 10 Gbps operation.
