Part Number: OPT3101

I. would like to ask how to calculate the τ（calibration delay time ) of Internal Crosstalk calibration.  Is the  τ（calibration delay time ) 2.048s?

2..And is NUM_AVG_SUB_FRAMES at least 2 of the 10 power frame?

    Hi,

    All the info you need you should be able to find in our calibration doc: www.ti.com/.../sbau310.pdf
    Have you had a chance to read through this doc? Please let me know if you did not know about this doc and we need to make it more visible.

    The time constant formula is equation 6. Also see the paragraph above the equation "For accuracy, at least 2
    10 subframes should be allowed for filter averaging"

    Best,

    Alex
