TIM home page

The TIM ( TTC Interface Module ) is the interface between the SCT off-detector electronics and the ATLAS Level-1 trigger. Each crate of ROD ( Read-Out Driver ) modules contains a TIM, which receives the TTC ( Timing, Trigger, and Control ) signals, and transmits the required information to the RODs via a custom backplane. The TIM is also capable of stand-alone operation, generating the signals as requested by the local processor.
