The TDCs (Time-to-Digital Converters) family provides high-precision timing measurements for nuclear, particle physics, and detector characterization applications. Designed for multi-channel systems and high-rate environments, these modules convert the time interval between reference and detector signals into digital data with picosecond-level resolution.

Supporting multi-hit operation, leading/trailing edge detection, and programmable acquisition modes, the family enables accurate time tagging, time-over-threshold measurements, and coincidence analysis across large detector arrays. Advanced buffering, flexible readout architectures, and support for multiple logic standards ensure seamless integration into modern VME-based data acquisition systems and high-throughput experiments.

  • Picosecond-level timing resolution with multi-hit capability for high-precision measurements

  • Leading/trailing edge detection and programmable acquisition modes (trigger matching or continuous)

  • High channel density with deep buffers and fast VME/optical readout options

  • Compatible with multiple input standards (NIM, LVDS, ECL) for flexible system integration
