Abstract
The ATLAS level-1 calorimeter trigger will utilise a number of advanced tec hnologies, many of which have already been successfully demonstrated. To ev aluate the different technologies associated with the important areas of hi gh-speed data transport a large demonstrator system has been designed and o perated during the last two years, using signals from prototype calorimeter s in the ATLAS test-beam. Using this system, inter-crate data transmission and reception have been de monstrated at over 1.4 Gbyte/s, with individual links running at up to 1.6 Gbaud, Operating with 160 Mbit/s signals across a transmission-line backpla ne, custom transceiver ASICs have achieved inter-module data fanout at peak rates above 800 Mbyte/s. With the addition of Further modules, the system was extended to emulate a vertical slice through the ATLAS level-1 calorime ter trigger. We present here the results from these tests, including measurements of bit -error rates across different data paths.
