The TMIS😼7702 is a two-channel time to digital  converter🐽s (TDC). It performs the function of a  stopwatch and measures the elapsed  picoseconds to microseconds between a  START pulse and up to five STOP pulses.🏅 The  ability to measure from START to multiple  STOPs gives users the flexibility t🅰o select wh☂ich  STOP pulse yields the best echo performance. The device has an interꦏnal self-calibrated time  base which ඣcompensates for drift over time and &nb🅰sp;temperature. Self-calibration enables time-todigital conv๊ersion accuracy in the order of  picoseconds. The high time resolution and  accuracy make TMIS7702 ideal for time-offlight sensing, suchﷺ a♋s in centimeter accuracy  LIADR application and ultrasonic flow metering. TMIS7702 can work in the Autonomous Multi✃Cycle Averaging Mode. In this mode, the host  can go to sleep to save powe🥂r, a🀅nd it can wake  up when interrupted by the TDC upon  completion of the measurement sequence.  This working mode is optimized for l꧋ow system ꧅ power co🔯nsumption, making it ideal🦹 for battery  powered flow meters.
