Characterization and performance of a DAQ system for the readout of silicon pixel detectors

We have developed a data acquisition system for the parallel read-out of silicon pixel detector modules. The front-end electronics of the system is based on the VATAGP7, a Gamma Medica - Ideas application specific integrated circuit (ASIC). The acquisition board (MADDAQ) has an FPGA chip that controls the ASIC configuration and the readout process. Collected data is stored into internal memory and sent to a PC through an Ethernet connection. Several MADDAQ boards can work together independently or in coincidence mode. The system has the option to be synchronized with another setup like in a conventional PET scanner. The full characterization of the system is presented.
