Mass Production of a Trigger Data Serializer ASIC for the Upgrade of the Muon Spectrometer at the ATLAS Experiment

Abstract The Trigger Data Serializer (TDS) is a custom ASIC designed for the upgrade of the innermost station of the endcap ATLAS Muon spectrometer. It is a mixed-signal chip with two working modes that can handle up to 128 detector channels. A total of 6000 TDS ASICs have been produced for detector operation. This paper discusses a custom automatic test platform we developed to provide quality control of the TDS ASICs. We introduce the design, illustrate the test procedures, and discuss the experimental results.
