Alice Inner Tracking System Readout Electronics Prototype Testing with the Cern "giga Bit Transceiver"

The ALICE Collaboration is preparing a major detector upgrade for the LHC Run 3, which includes the construction of a new silicon pixel based Inner Tracking System (ITS). The ITS readout system consists of 192 readout boards to control the sensors and their power system, receive triggers, and deliver sensor data to the DAQ. To prototype various aspects of this readout system, an FPGA based carrier board and an associated FMC daughter card containing the CERN Gigabit Transceiver (GBT) chipset have been developed. This contribution describes laboratory and radiation testing results with this prototype board set.
