We describe the latest (last?) full functionality revision of the high-speed data link board for the ATLAS TileCal phase 2 upgrade. It is highly redundant, using two Kintex-7 FPGAs and two Molex QSFP+ electro-optic modules. The FPGAs are remotely configured through two radiation-hard CERN GBTx deserialisers (GBTx), which also provide the LHC-synchronous system clock. The four QSFP+ uplinks...

The high-luminosity phase of the Large Hadron Collider will provide a 5-7 times greater instantaneous and total luminosities than assumed in the original design of the ATLAS Liquid Argon Calorimeters and their read-out system. An improved trigger system with higher acceptance rate and longer latency and a better radiation tolerance require an upgrade of the read-out electronics. Concepts for...

For the Phase I upgrade of the CMS pixel detector a new digital readout chip (ROC) has been developed. An important part of the design verification are irradiation studies to ensure sufficient radiation tolerance. The presentation summarizes results of the irradiation study on the final ROC design for the detector layers 2 - 4. Samples have been irradiated with 23 MeV protons to accumulate the...
