I would like to use the TDC7200 to measure the time-of-flight between two particle pulses from spatially separated light sheets, but I have some questions. The time difference between the rising edge of the START pulse and the rising edge of the STOP pulse is expected to be about 1 us or more. All the examples I've seen show square-edged pulses with very fast rise/fall times. The data sheet only lists T_RST, T_FST (max rise, fall time) as 1 ns NOM. My pulses have a 1 us rise time and a >10 us fall time. Could I use the TDC7200 with such pulse timing? Also, my pulse amplitudes are on the order of 100s of millivolts. What pulse amplitude is expected? If my pulse timing and amplitude is inadequate, I would likely need to condition the pulses to provide what is necessary, i.e., by using a comparator or similar. It is conceivable that the START and STOP pulses would overlap if the TOF is < 10 us. I need to understand the pulse requirements for the START and STOP pulses supplied to the TDC7200.
