We would like to understand What happen if SumScale value is over (datasheet)Table 54 recommendation?
Does it make MER/EVM poor or any concern about it? thanks!!
It could. it depends on whether you saturate the input to the DAC or not. The Sum Scale is there to scale your digital signals such that, when added together, they don't exceed the max DAC value. The recommended values for Sum Scale take into account the peak-to-average ratio of the signals being added to make sure the saturation does not occur.
