Part Number: TDC7200

I am trying to design the circuit to integrate the chip and not clear what the result will be if

STOP pulse before Start

Multiple START pulse

Please help to understand.

Hello,

Whenever you have multiple start pulse, the ToF will be calculated as the time between the first START pulse & first STOP pulse.

Incase your stop pulse is before the start pulse, the system will not see it and will time out.

So basically more Start pulse is ignored after the first as I understand.

The 2nd question is the separate condition. My circuit has a lot of STOP before START since I am selecting the particular period to measure. Again, the STOP before START is ignored as I understand.

Please let me know if my understanding is correct.

Thanks!
