TDC1000

The TDC1000 is a high-precision time-to-digital converter (TDC) designed by Texas Instruments for applications requiring accurate measurement of time intervals. It features an internal 32-bit counter and supports resolutions down to 50 picoseconds, enabling precise timing measurements across a wide dynamic range. The device integrates a low-jitter clock generator and a flexible trigger interface that allows both rising and falling edge detection for input signals. This TDC offers excellent noise immunity and stability over temperature, making it suitable for harsh environments. It includes on-chip calibration circuits to minimize offset and gain errors, ensuring consistent performance without external adjustments. Communication with the TDC1000 is achieved via a standard SPI serial interface operating up to 50 MHz, allowing fast data transfer and integration into existing system architectures. Key features include programmable resolution settings, multiple input channels for simultaneous measurements, and support for various signal types including TTL, LVCMOS, and differential inputs. The device also incorporates built-in diagnostics such as self-test functionality and error flags, which enhance system reliability and simplify troubleshooting during operation. The TDC1000 is commonly used in scientific instrumentation, precision metrology, and industrial automation where accurate time-of-flight or phase-based measurements are critical. Applications include laser ranging, ultrasonic sensing, gas analysis, and time-of-flight mass spectrometry. Its compact form factor and low power consumption make it ideal for portable and battery-powered systems. In addition, the TDC1000 supports flexible configuration through software registers, allowing users to tailor timing parameters for specific use cases. It can be easily interfaced with microcontrollers or FPGAs, providing a scalable solution for both prototyping and production environments. With its robust design and extensive feature set, the TDC1000 delivers reliable, high-resolution timing performance across diverse engineering applications.
