Abstract
Time to Digital Converters has been used to measure time difference between two events with high accuracy and resolution approx. 100 ps. In this paper, it is proposed to develop a data acquisition system for Time-of-Flight measurement using Time to Digital converter. The firmware for the system is designed around PIC 18F4550 microcontroller and TDC7200 integrated circuit. The system has been programmed to configure Time to Digital Converter using SPI line and log out the acquired data over to PC via UART. The readout system has been tested with calibrated delay inputs to examine the different working modes of operation. The gathered data has been analyzed using ROOT framework. The cost effective alternative for the Time to Digital Converter evaluation module also has been discussed and designed to be compatible with microcontrollers as well as Field Programmable Gate Array devices.
