概要
Description
TDC-GPX is a time-to-digital converter (TDC) product family used to timestamp fast electrical events with high precision. It typically provides multiple input channels, sub-ns to few-ps resolution through a coarse counter plus a fine interpolation (delay-line or vernier-based timing network), and supports common-stop, start-stop, or multi-stop timing modes. The device usually includes programmable thresholds, input conditioning, dead-time control, self-calibration, and an on-board memory or streaming interface. Data are read out by a host via USB, Ethernet, or PCIe, with a software API for configuration and data handling. Applications include time-of-flight measurements, scintillator detectors, PET, LiDAR, fluorescence lifetime, and single-photon counting. When selecting a TDC-GPX, consider required channel count, time resolution, maximum event rate, jitter, calibration stability, power, and compatibility with your detector signals (NIM/TTL/LVDS) and data interface. If you have a specific model or vendor, I can tailor the details.
Pinout
Pin count: 28 pins (typical package: 28‑pin QFN/LQFP). Function: Time-to-Digital Converter (TDC) that measures time intervals (start–stop) with high resolution and outputs the result via a serial interface (e.g., SPI). Key pins include START, STOP/TRIG, CLK, CS, MOSI/MISO (or SO/SI), VCC, and GND; exact pin names depend on the chosen package.
Manufacturer
The TDC-GPX is manufactured by ACAM GmbH. ACAM is a small-to-mid-sized German electronics company that specializes in precision timing and measurement electronics, including time-to-digital converters (TDCs) and related instrumentation for scientific and industrial use.
