A 65 Nm Data Concentration ASIC for the CMS Outer Tracker Detector Upgrade at HL-LHC

The Concentrator Integrated Circuit (CIC) ASIC is a front-end chip for both Pixel-Strip (PS) and Strip-Strip (2S) modules of the future Phase-II CMS Outer Tracker upgrade at the HighLuminosity LHC (HL-LHC). It collects the digital data coming from eight upstream front-end chips (either MPAs or CBCs, depending on the module type), formats the signal in data packets containing the trigger information from eight bunch crossings and the raw data from events passing the first trigger level, and finally transmits them to the LpGBT unit. The design and its implementation in a 65 nm CMOS technology of the first prototype that integrates all functionalities for system level operation are presented in this contribution.
