前端驱动器是一个9 U 400 mm VME 64 x卡，设计用于阅读APV 25模拟管道ASIC传输的CMS硅跟踪器信号。FED通过96根光纤以3.4千兆比特/秒的总输入速率接收信号。信号被数字化并通过应用用于消隐和共模噪声减法的算法进行处理。使用搜索命中聚类的算法来进一步降低输入率。只有集群数据沿着事件的触发信息使用S-LINK 64协议以400 Mbytes/sec的最大速率传输到CMS DAQ系统。FED上的所有数据处理算法都在大型板载FPGA中执行。FED的设计，性能，测试和质量控制的结果，并进行了讨论。
The front end driver is a 9U 400mm VME64x card designed for reading out the CMS silicon tracker signals transmitted by the APV25 analogue pipeline ASICs. The FED receives the signals via 96 optical fibers at a total input rate of 3.4 GBytes/sec. The signals are digitized and processed by applying algorithms for pedestal and common mode noise subtraction. Algorithms that search for clusters of hits are used to further reduce the input rate. Only the cluster data along with trigger information of the event are transmitted to the CMS DAQ system using the S-LINK64 protocol at a maximum rate of 400 Mbytes/sec. All data processing algorithms on the FED are executed in large on-board FPGAs. Results on the design, performance, testing and quality control of the FED are presented and discussed.
