ADN4605- Any constrain on the Input when using Polarity inversion

Dear Supporter

Regarding the ADN4605 polarity inversion:

IF we connect the outputs directly as defined by datasheet we need to swap the signal on the PCB which makes the layout more difficult. As defined in datasheet we can swap the positive and negative outputs pins of the same differential output.

My question is does it has any constrains on the input signal?

For example if I route differential input 1 with positive to positive and negative to negative, and at the output 1 I connect positive to negative and negative to positive pins will this scenario work only by writing to the TXSIGN bit of the TX control registers that OUT1 inverts the polarity?
