Precision time digital converter (i.e., TDC) is a crucial technique for sensing and detecting and is frequently employed in a variety of contexts, including inertial navigation, aviation, space physics, and optical fiber communication. However, the implementation of a stable and uniform delay line and the accurate time interpolation are frequent trouble in the implementation process but are hardly ever analyzed as a whole. In order to develop a full and exact system, this manuscript examines the two primary issues and offers practical solutions. The system is tested in the low-cost FPGA of the Altera Cyclone IV series. According to the test results, the precision TDC system performs admirably, with an RMS accuracy of approximately 18.54 ps.
