Hi,
I wanted to confirm that −6 dBFS is the maximum recommended level at the TX SSI interface of the ADRV9002 when all calibrations are enabled.
In the chapter on Digital Predistortion, in guidelines for “Measuring the CLGC Target Gain.”, there is a reference to the peak transmit signal amplitude at the DAC (rather than at the SSI interface).

I am not sure whether this value should also be applied to the maximum input level at SSI.
In datasheet there are messurments taken even at only 0.2dBFS backoff.
