A flexible electronics and DAQ system for the Timepix4 ASIC

Abstract

The INFN Data Acquisition system (IDAQ) is designed for data-driven readout of the Timepix4 ASIC, supporting simultaneous time-of-arrival and time-over-threshold measurements with nanosecond precision. The system architecture combines dedicated hardware for high-speed serial data transmission, FPGA-based data processing, and a Trigger Logic Unit for synchronization and timing distribution. It operates in continuous streaming and triggered modes, ensuring low-latency and high-throughput performance. The system has been deployed in test-beam campaigns within the 4DPHOTON project, demonstrating stable operation, precise timing alignment, and reliable data handling under high-rate conditions.
