本文介绍的探测器读出结构适用于具有中等带宽需求的中小型物理实验，以及对探测器附近部分的本底放射性要求最终较低的应用。简化读出系统和最小化材料预算的第一个想法是使用公共扇出结构来从非检测器后端电子器件传输前端电子器件的同步、配置和读出所需的所有流量。第二个想法是在每个前端卡和后端电子设备之间使用点对点链路，该链路以相对较低的速度运行，足以满足目标应用程序的要求。这拓宽了通信链路物理介质的可能选择，例如玻璃纤维、塑料光纤或铜。本文提出了一种适合于非对称网络的通信协议，并利用廉价的商用FPGA模块设计了一个能够控制32个前端单元的后端单元，总带宽高达12.8Gbps，其中大量的常规I/O引脚与前端链路接口，而少数可用的每秒数千兆位的收发器影响了与DAQ系统上层的通信。

英文摘要：
  The detector readout architecture introduced in this paper is intended for small to medium size physics experiments that have moderate bandwidth needs, and applications that require an ultimately low background radioactivity for the parts close to the detector. The first idea to simplify the readout system and minimize material budget is to use a common fanout structure to transport from the off-detector back-end electronics all the traffic required for the synchronization, configuration and readout of the front-end electronics. The second idea is to use between each front-end card and the back-end electronics a point-to-point link that runs at the relatively low speed that suffices for the target application. This broadens the possible choices for the physical media of the communication links, e.g. glass fiber, plastic optical fiber, or copper. This paper presents a communication protocol adequate for the proposed asymmetric network and shows the design of a back-end unit capable of controlling 32 front-end units at up to 12.8 Gbps of aggregate bandwidth using an inexpensive commercial FPGA module where the large number of regular I/O pins interface to the front-end links, while the few available multi-gigabit per second capable transceivers are affected to the communication with the upper stage of the DAQ system.
