The High Luminosity Large Hadron Collider (HL-LHC) will have a peak\nluminosity of 5\×1034 cm-2 ,s-1, five times higher than the\ndesign luminosity of the LHC. The hadronic ATLAS Tile Calorimeter TileCal) is a\nsampling calorimeter with steel as absorber and plastic scintillators as active\nmedium. The light produced in the scintillating tiles is guided to\nphotomultiplier tubes (PMTs), where analogue signals are produced to be shaped\nand conditioned before being digitized every 25 ,ns. TileCal Phase-II Upgrade\nfor the HL-LHC will allow the system can cope with the increased radiation\nlevels and out of time pileup. The upgraded system will digitize and send all\nthe calorimeter sampled signals to the off-detector systems, where the events\nwill be reconstructed and shipped to the first level of trigger, all at 40 ,MHz\nrate. Consequently, development of more complex trigger algorithms will be\npossible with the more precise calorimeter signals provided to the trigger\nsystem. The new hardware comprises state of the art electronics with a\nredundant design and radiation hard electronics to avoid single points of\nfailure, in addition to multi-Gbps optical links for the high volume of data\ntransmission and Field Programmable Gate Arrays (FPGAs) to drive the logic\nfunctions of the off- and on-detector electronics. A hybrid demonstrator\nprototype module containing the new calorimeter module electronics, but still\ncompatible with the present system was assembled and inserted in ATLAS during\nJune 2019, so that the Phase-II system can be tested in real ATLAS conditions.\n
