Working Principles

The TDC1000QPWQ1 utilizes a time-to-digital conversion technique based on the measurement of the time-of-flight (TOF) of a signal. It employs a reference clock to generate precise time intervals, which are then compared with the incoming signal's TOF. The resulting time difference is converted into digital data using high-resolution circuitry.
