TDC-GPX

TDC-GPX is a high-precision time-to-digital converter (TDC) platform used to timestamp events with sub-nanosecond resolution. It converts the time interval between input events (start/stop or multi-hit) into digital codes, typically using an FPGA-based coarse counter plus a fine timing structure (e.g., delay-line or DLL) for picosecond to sub-ns resolution.
Key features (typical, model-dependent):
- Multi-channel inputs (4–32+ channels)
- Fine and coarse timing: ps–ns resolution
- Multi-hit capability and scalable channel counts
- On-board calibration and timing alignment
- FPGA-based data processing and custom firmware
- Various data interfaces: USB, Ethernet, PCIe (and LVDS/CMOS I/O)
Common applications:
- Time-of-flight measurements (ToF)
- Scintillator and particle detectors, PET
- LIDAR and depth sensing
- Fluorescence lifetime imaging and other fast-timing experiments
- Synchronization in multi-channel measurement systems
Getting started (high level):
1) select the model, 2) connect sensors, 3) configure firmware/parameters, 4) calibrate timing, 5) acquire and analyze data.
Note: exact specs vary by model; consult the vendor datasheet for precise resolution, channels, and data formats.

Which exact TDC-GPX model/vendor? The package type varies by model (e.g., QFN, LQFP, QFP, or a module/board form). Please provide the part number for precise packaging information.

Typical application areas of TDC-GPX:

- High-energy physics (event time-stamping, trigger systems)
- Time-correlated single-photon counting and fluorescence lifetime imaging
- TOF mass spectrometry
- Optical fiber sensing and OTDR
- Precise timing and synchronization in data acquisition and communications
- Quantum optics experiments requiring accurate photon timing
