I am going to use the TDC7200 to time the time-of-flight (TOF) between a transmitted and reflected RF pulse (Radar). From the data sheet and User's Manual it is unclear as to how fast the TDC7200 can be ready for another START pulse after receiving the previous STOP pulse to process and send out the TOF calculation serially to a receiving unit. In other words, what is the maximum RF pulse rate I can send out and ensure the TDC7200 will be ready to begin a timing cycle without missing the START signal. 100Hz, 1000Hz, 1MHz?? I understand it can't be less than the measured TOF but let's assume the measured TOF is 40nsec. How much time do I need after the reception of the STOP signal to have the TDC7200 ready to receive another START signal for the next RF pulse?? Any help answering this question will be greatly appreciated.
Sincerely,
Mike
