| Abstract | The CMS ECAL barrel is set to undergo a substantial upgrade to meet the new and more challenging requirements of the High-Luminosity LHC (HL-LHC) accelerator. This upgrade involves a comprehensive redesign of the on-detector readout electronics, introducing new faster ASICs. The upgraded readout architecture will consist of a fast trans-impedance amplifier, called CATIA, and a two-channels 12-bit 160 MS/s ADC and a data selection and compression ASIC, called LiTE-DTU. The output of each readout channel is a single 1.28 Gbps serial line, which is connected to an e-link of the lpGBT radiation tolerant transceiver. The data from all readout channels will be sent to an FPGA based data processor located outside the LHC cavern. Extensive testing has been carried out at both ASIC and system levels, demonstrating the readiness of all the prototypes and the systems ability to meet the time and energy resolution requirements, also in beam test settings. The highlights of these tests will be presented. |
