1 1 Calorimeter Trigger to L1-Board data transmission Umberto Marconi INFN Bologna

2 U. Marconi INFN, Bologna 2 Interfacing to L1  The upgrade path to the final L1 system foresees, at some point, the usage of the ECAL and HCAL clusters  With this aim in mind the Selection Boards of the Selection Crate have been re-designed adding them the following features  L0 buffer with tuneable depth (160 clock max)  L0 derandomizer  A GOL based output single channel optical transmitter  The Selection Crate uses 8 Selection Boards  We need 8 optical links to connect the Calorimeter Trigger to L1 through 1 L1 Board
