Test and performance of the LiTE-DTU ASIC for the HL-LHC upgrade of the CMS ECAL barrel

A data conversion and compression ASIC, named LiTE-DTU, has been developed for the upgrade of the CMS electromagnetic calorimeter (ECAL) for the High -Luminosity phase of LHC. The ASIC integrates two 12 -bit 160 MS/s ADCs, a data processing unit for gain selection and data compression, and a 1.28 Gb/s serializer. The ASIC has been extensively tested in laboratory and in beam tests showing excellent yield and performance. The radiation tolerance has been verified with dedicated test campaigns for both total ionizing dose and single event effects. Results from these tests, showing the design readiness for mass production, will be presented.
