Performance of the Read-Out Driver for the RPCs Muon Spectrometer of the ATLAS experiment

The ATLAS detector at CERN’s LHC will be exposed to proton-proton collisions from beams crossing at 40 MHz with an energy of 14 TeV. A complex multilevel Trigger and Data Acquisition (TDAQ) system have been designed and built in order to reduce the event rate from about 10⁹ interactions per second to about 200 Hz, storing data with a rate of about 400 Mb/s. The first element in the data acquisition chain is the Read-Out Driver, which is specific for each ATLAS subdetector.
