AD9363 unused TX output issuu

Hi Stanislav3S88 

Our standard recommendation for Tx unused ports should be tied to 1.3V. if there are any leakages from unused ports and we might see the performance degradation in the Tx channel.

Is there any way to mitigate the effects of this issue through software or device configuration? For example, can the unused TX2B path be disabled or powered down to minimise any impact caused by leaving the TX2B outputs unconnected?

HI Stanislav3S88 ,

We have selection of the port for both channels with single register bit bool value. These are selected from mux selection bit. You cannot independently switch off the section.

It is better to properly biased to have no leakages. This cannot solve through software configuration.
