在高能量物理学和核物理实验中，尤其是基于粒子加速器的实验，检测器的数据速率通常是按照探测器前端电子学（FEE）的这些高吞吐量数据的顺序。传输到后端计算农场，以进行高级事件的选择和构建。简化整个实验的读数架构。除了双向高速光纤链接的48个渠道外，有利于可扩展的探测器的商业硬件和软件的定制硬件数量与实验正时系统同步，并以固定的延迟到费用触发时钟并触发信息。
In high energy physics and nuclear physics experiments, particularly the ones based on a particle accelerator, the data rate from the detector is usually in the order of terabytes per second. These high throughput data from detector front-end electronics (FEEs) need to be transmitted to the back-end computing farm for high-level event selection and building. A data acquisition (DAQ) system with the features of high density, scalable, and easily upgradeable is crucial to simplify the readout architecture of the whole experiment. This article will introduce the design of a generic high bandwidth PCIe card, which can be used as the important input–output card in a scalable DAQ system. It can factorize FEEs from data handling and reduce the amount of custom hardware in favor of scalable detector-independent commercial hardware and software. Besides the 48 channels of bidirectional high-speed fiber optical links with front ends, it also supports to synchronize with the experiment timing system and to fan-out the clock and trigger information with a fixed latency to the FEEs.
