A new readout electronics for the LHCb Muon Detector Upgrade

The 2019 upgrade of LHCb Muon System foresees a trigger-less 40 MHz readout scheme and requires the development of a new Off Detector Electronics (nODE) board, based on the nSYNC, a radiation tolerant custom ASIC developed in UMC 130 nm technology. The muon readout electronics has the purpose to process the digital signals from the front-end electronics, performing bunch crossing alignment, data zero suppression, time measurements. With respect to the current system, the new boards will allow a muon system readout at 40 MHz (the bunch crossing frequency at LHC), thanks to the nSYNC functionnalities, and the new optical communication system based on the GBTx driver/serializer chipset.
