Design of a Data Concentrator Card for the Readout of the Compact Muon Solenoid Electromagnetic Calorimeter

The data concentrator card (DCC) is part of the readout electronics of a particle physics detector. The DCC project is a multi-project project involving high-speed design, built-in testability, data processing with data reduction techniques, low-jitter clock distribution, power supply regulation and filtering and implementation of multiple FPGAs on a 9U multilayer printed circuit board. The DCC collects data from various sources and after processing transmits the resulting data to a central data acquisition system (DAQ). The validation of the DCC required the design of a specific test system that emulates the detector functionality. To cover all the experiment needs we had to produce 60 similar boards. In this paper we summarize the design architecture and functionality of the DCC, the developed test bench and present the production status.
