After a long design and development, a prototype of the pixel detector front-end readout chip is proposed for the HL-LHC ATLAS and CMS upgrades. It provides data streams using up to four lanes running at 1.28 Gbps each. In parallel to that, an off-detector high-speed electronic readout system card, namely FELIX, has been developed and proposed to be shared among the ATLAS sub-detectors. This paper describes in detail the implementation of a full readout chain for the front-end readout chip, namely the RD53A, using the current ATLAS Phase-II readout FELIX card. For this work the readout chain has required dedicated electronics as a hardware interface between the front-end chip and the off-detector readout. Moreover, to maximize the efficiency of testing the chip and to realize the readout chain, it is extremely important that, even for the first prototypes, the DAQ chain is as similar as possible to the final one. The implemented chain has been left available at CERN for further tests and developments for the entire ATLAS TDAQ collaboration. This readout chain is proposed as a general readout test-stand for Large-Scale Application of pixel detectors. Full details of the prototype and testing performed to date are presented.

经过长时间的设计和开发，提出了用于HL-LHC ATLAS和CMS升级的像素检测器前端读出芯片的原型。它使用多达四个分别以1.28 Gbps运行的通道提供数据流。与此并行，已经开发出一种探测器外高速电子读出系统卡，即FELIX，并提议在ATLAS子探测器之间共享。本文详细介绍了使用当前ATLAS Phase-II读出FELIX卡实现的前端读出芯片RD53A的完整读出链。为此，读出链需要专用的电子设备作为前端芯片和关闭探测器读出器之间的硬件接口。此外，为了最大程度地提高芯片测试的效率并实现读出链，极其重要的是，即使对于第一个原型，DAQ链也与最后一个原型尽可能相似。已实施的链条已留在CERN，可用于整个ATLAS TDAQ合作的进一步测试和开发。该读出链被提议作为像素检测器大规模应用的通用读出测试台。展示了原型的完整细节和迄今为止进行的测试。
