• Overview of the calorimeter readout electronics: each disk (~ 680 crystals per disk) is subdivided into 34 groups of 20 crystals.
•
q Groups of 20 left (right) Amp-HV chips, controlled by a dedicated mezzanine board (MB) that distributes the LV and the HV reference value, while setting and reading back the locally regulated voltage
q Groups of 20 amplified signals are sent to a digitizer module (WD) where they are sampled and processed before being optically transferred to the DAQ system.

Stato e prospettive della mezzanina • Firmware completo al 80% • Progetto hardware dell’intero sistema completato • Studio e realizzazione layout 90% • Implementazione interfaccia I2C in corso • Produzione di 5 prototipi entro fine settembre
• Test della scheda previsto per metà ottobre • Test dell’intero sistema, previsto inizio novembre

Conclusions
23
• The front-end system amplifies the SiPM signals and provides HV setting and regulation, in a Voltage range below 200 Volt.
• The cables and the connectors,between Amp-HV and MB boards have been defined (differential output). Cables should have lengths smaller than two meters in agreement with the cabling layout.
• For the preamp-regulator chip ! the project is complete. Minor adjustment for connectors. New production of 20 pieces now.
• FEE pre-production and test done for Module-0. Project for the MB board in final layout in progress now. Expected for November.
• External HV/LV power supplies are being discussed with CAEN, following recommendation from Integration group.
