TDA4VE-Q1: CCM Matrix RC,GC, BC Values

TDA4VM: CCM Matrix max values

Part Number: TDA4VM

Hi Experts,

I am currently working on the CCM tuning for AR0820 image sensor.
In the manual tuning method, we have the CCM matrix to update.
In that matrix the max value we can give is 1023.Is this limit having any logical meaning? why not any other value as a max value?

Thanks.

    Hi Ajay,

    It valid range of values is limited the corresponding VISS H/W registers.
    The supported range on H/W should be -2048~2047 if I recall correctly.

    It seems tuning tool has put some additional constraints.

    If you need to input values below -1024 or above 1023, you may edit the xml output files directly.
