The High Luminosity Large Hadron Collider (HL-LHC) has motivated R&D to upgrade the ATLAS Tile Calorimeter. The new system consists on an optimized analogue design engineered with redundancy layers to avoid single points of failure. The design will provide better timing, improved energy resolution. Multiple types of FPGAs, CERN custom radhard ASICs (GBTx), and multi-Gbps optical links are used to distribute LHC timing, read out fully digital data of the whole TileCal. To test the upgraded electronics in real ATLAS conditions, a hybrid demonstrator prototype module containing the new calorimeter module electronics, but still compatible with TileCal legacy system. Here is presented main components of the Demonstrator and how they work.
