在Atlas，CMS和Alice的技术建议中，需要数千个数据链接。尽管显然需要进行标准化，但由于链接以不同的速度，不同距离的速度运行，并且具有各种限制功耗，大小和辐射硬度，因此这似乎很难实现。另一个复杂的是，今天我们无法决定哪种最具成本效益的技术来实施最终链接。此外，我们必须允许在链接的每一端（例如读取电子和输入缓冲区）的板设计人员与链接的开发并行工作。 S-Link是一个新概念，应在没有限制的情况下提供标准化的好处。 S-Link规范在链接的两端定义了一个简单的类似FIFO的用户界面，该界面仍然独立于用于实现物理链接的技术。物理链接提供事件数据和控制单词，错误检测，可选流量控制和测试设施的传输。本文介绍了S-Link规范，并举例说明了S-Link设计的S-Link的使用以及正在开发的测试设备。
In the Technical Proposals for ATLAS, CMS and ALICE there is a requirement for several thousand data links. Although there is an obvious need for standardisation, this seems difficult to achieve as the links run at different speeds, over different distances and have various constraints of power consumption, size and radiation hardness. An additional complication is that today we cannot decide which will be the most cost effective technology for the implementation of the final links. Furthermore, we must allow designers of boards at each end of the link, for example readout electronics and input buffers, to work in parallel with the development of the links. The S-LINK is a new concept which should provide the benefits of standardisation without the limitations. The S-LINK specification defines, at both ends of the link, a simple FIFO-like user interface which remains independent of the technology used to implement the physical link. The physical link provides transfer of event data and control words, error detection, optional flow control and test facilities. This paper describes the S-LINK specification and gives examples of the use of the S-LINK the physical links being designed, and the test equipment that is being developed.
