Other Parts Discussed in Thread: OPT9221

I'm working at ToF project based on OPT8241 and Evaluation kit. and now I am studying how OPT8241 works.

by the way, I could not find what is A+B and A-B which is out from CMOS Output interface

i want find out what is A and B and why the data is sent in A+B or A-B format.

Thank you.

A and B are a pixel's photo electron collectors. See this document for detail.

A-B encodes the depth information. A+B encodes the ambient information.

thank you for your answers

it means A is related to charge in gate of DMIX0 and B is to gate of DMIX1 right?

I have a one more question

what is Channel 1 and Channel 2 in the above picture?

Please see this video for more detail explanation on how the pixel works. I will check with my colleague on the chan0 and chan1 question.

Please note that TI currently does not support standalone operation of OPT8241. It is to be used in conjunction with OPT9221.
