MS1022 Time-to-Digital-Converter Overview MS1022 is next generation’s upgrade for MS1002. It is a 100% pin-to-pin and functional compatible upgrade of MS1002, with an extended functionality. The new first wave detection capability makes the MS1022 perfectly suited for ultrasonic water meters .The programmable offset range of the comparator is increased to ± 35 mV and the offset is automatically set back to zero after the first wave detection. Measuring the first wave gives the user an indication of the strength of the received signal. It can be used for adopting the system to longterm signal attenuation or for bubble detection.
