Description
To meet the stringent demands of signal digitization in high-energy physics experiments, a universal high-speed digitizer module has been developed for precise acquisition of fast analog signals from various detector technologies. The system supports sampling rates of up to 20 GS/s in single-channel mode and 10 GS/s in dual-channel mode, offering 9 GHz analog bandwidth and 12-bit vertical resolution. It is optimized for use with fast-response detectors such as silicon sensors and photomultiplier tubes, where accurate time-resolved signal capture is essential. Multi-module synchronization enables scalable architectures for multi-channel acquisition or increased temporal resolution via interleaved mode, where two modules are phase-shifted to achieve an effective sampling rate of up to 40 GS/s. Data interfaces include USB 3.0 and optical link; in the latter case, an FPGA-based PCIe interface card installed in the data acquisition PC handles the optical-to-PCIe protocol conversion. The digitizer is supported by a modular DAQ software suite featuring desktop (window), console, and web-based control applications, and is fully integrable into complex distributed DAQ systems. The architecture supports flexible triggering, acquisition length control (signal-based or time-based), optional on-board preprocessing, and a design optimized for radiation tolerance. The device provides a robust and versatile solution for high-rate signal digitization in front-end electronics for modern detector systems.
