<table bgcolor="#f5f5fa" border="1" cellpadding="10" cellspacing="10" style="width: 100%;"> <tbody> <tr> <td bgcolor="#eeeeee">The analog pulses from the PMTs undergo shaping and amplification in the 3-in-1 cards in two gains (low and high) with a ratio of 1:64. Low gain signals which are summed in groups by adder boards are provided to the Level 1 Calorimeter Trigger. The analog pulses are received by digitizer boards where the signal is converted into digital samples every 25 ns, which are stored in the front-end pipeline memories, the so called Data Management Units (DMU). Upon Level 1 accept, an event-frame-selector selects high gain samples unless the highest sample is saturated in which case the low gain samples are used and stores them in a buffer. Event frames are pulled from the DMUs by the Interface card which formats the data and transfers the frames to the off-&#144;detector Read-&#144;Out Drivers (RODs).<br /> *Contact:* =Carlos.Solans@cern.ch= and =Alberto.Valero@cern.ch= <br /> *Reference:* [[https://indico.cern.ch/conferenceDisplay.py?confId=206212][ATLAS Tile weekly operations meting (01/11/12)]] [[https://cdsweb.cern.ch/record/1489969][ATL-COM-TILECAL-2012-048]] <br /> *Date:* 1st November 2012</td> <td align="center"><img alt="Diagram of the Tile front-end electronics" src="%ATTACHURLPATH%/tile_frontend_cartoon.png" width="343" /> <br /> [[%ATTACHURLPATH%/tile_frontend_cartoon.pdf][pdf]]</td> </tr> <tr> <td bgcolor="#eeeeee">The front-end electronics is divided in eight identical Digitizer Boards reading 6 PMTs each. The analog pulses are received by the Digitizer Board where the signal is converted into digital samples every 25 ns, which are stored in the front-end pipeline memories in the the so called Data Management Units (DMU). Upon Level 1 accept, an event-frame-selector selects the samples and stores them in a buffer. Event frames are pulled from the DMUs by the Interface card which formats the data and transfers the frames to the off-detector Read-Out Drivers (RODs) through optical fiber. The Digitizers are chained to transmit the data from the outermost boards t the Interface Card placed in the center of the SuperDrawer. Low gain analog signals which are summed in groups by adder boards are provided to the Level 1 Calorimeter Trigger. The Trigger, Timing and Control (TTC) signals are received are received by the front-end through optical links in the Interface Board which broadcasts the signals to the Digitizer Boards. <br /> *Contact:* =Carlos.Solans@cern.ch= and =Alberto.Valero@cern.ch= <br /> *Reference:* [[https://indico.cern.ch/conferenceDisplay.py?confId=206217][ATLAS Tile weekly operations meting (06/12/12)]] [[https://cds.cern.ch/record/1500099][ATLAS-PLOT-TILECAL-2012-013]] <br /> *Date:* 10th January 2013</td> <td align="center"><img alt="Architecture of the Tile read-out electronics" src="%ATTACHURLPATH%/Superdrawer_architecture.png" width="343" /> <br /> [[%ATTACHURLPATH%/Superdrawer_architecture.pdf][pdf]]</td> </tr> </tbody> </table>
