“…The PILUP has been proposed as part of the ATLAS TDAQ read-out system for the new RD53a front-end chip [8] that will upgrade the Pixel detectors of ATLAS and CMS. Four types of data protocol have to be handled in order to set up the communication between the FELIX cards and RD53a: the GBT protocol [9] developed by CERN (output of the FELIX, with bandwidth of 4,8 Gb/s) and the Full-Mode protocol developed by the FELIX group (input of the FELIX, with bandwidth of 9,6 Gb/s), which are the protocols used by the FELIX cards, the Aurora 64b/66b protocol (output of the RD53a, with a bandwidth of 5,12 Gb/s divided in 1,28 Gb/s for each of 4 lanes) and a 160 Mb/s data lane (input of the RD53a) for the RD53a.…”
