| Abstract | As part of the CMS Phase-2 upgrade, a prototype receiver for the HGCAL endcap front end has been implemented using the Serenity ATCA platform. The receiver firmware was developed to test the unpacking of data from the front-end endcap trigger concentrator ASIC (ECON-T) and measure its performance and stability. The firmware was integrated with prototype DAQ firmware as well as ancillary blocks to generate a trigger using ECON-T data, process scintillator trigger and timing distribution system, to evaluate the complete HGCAL vertical slice. The data was read out using custom 10G UDP links and upgraded to CMS DTH system at 25 Gbps. The system successfully achieved prototype TPG Stage-1 and DAQ path readout using generated beam triggers and delivered 20 TB of data containing physics events at an average trigger rate of about 100 kHz. |
