The CMS Drift Tubes readout system has been upgraded during the 2017-2018 technical stop to a new MicroTCA-based system to deliver the performance required by the increase of LHC luminosity. It comprises 3 µTCA crates with up to 25 boards, each processing 3 sectors from each CMS wheel. The µROS board is built around a Virtex-7 FPGA, and is able to receive 72 input links. The 240-Mbps inputs are deserialized using oversampling and adaptative phase detection. Event building, synchronization, data integrity monitoring and error correction have been implemented. The uROS system is fully operational, taking collision data satisfactorily.

Abstract
The CMS Drift Tubes readout system has been upgraded during the 2017-2018 technical stop to a new MicroTCA-based system to deliver the performance required by the increase of LHC luminosity. It comprises 3 µTCA crates with up to 25 boards, each processing 3 sectors from each CMS wheel. The µROS board is built around a Virtex-7 FPGA, and is able to receive 72 input links. The 240-Mbps inputs are deserialized using oversampling and adaptative phase detection. Event building, synchronization, data integrity monitoring and error correction have been implemented. The uROS system is fully operational, taking collision data satisfactorily.
