OPT8241: Minimum exposure time of OPT8241?

Hi,

What is the minimum exposure time of OPT8241? I couldn't find this in the datasheet.

Also could you give me the data for reset and read out time for each quad please?

Thanks.

    Hi Jongho,

    The minimum exposure time for each quad is 1024 clock cycles of 48MHz.

    Please refer to the OPT9221 datasheet section 7.3.3.2 for reset and readout time details. For easy reference, reset time is 768 clock cycles. And readout is given by Equation 4,5.

    For number of columns greater than total number of
    columns divided by 2:

    For number of columns lesser than half of the total number of columns:

    Preparation time = 401 + total number of columns (Measured in system clock cycles)
    Hope this helps.

    Regards,
