In our design we are not using the some of the sections. Is there any recommendation for those pins.


1. What is recommendation for unused SnRxA+/SnRxA-, SnRxB+/SnRxB-,SnRxC+/SnRxC-? Can i ground them directly.

2. What is recommendation for unused pins of  RX_EXTLO+/RX_EXTLO-, TX_EXTLO+/TX_EXTLO-?

3. Seems the reference design not uses the VRX_VCO_LDO(internal LDO) is it because the voltage of 1.1V supply.

4. Any recommendation on Sniffer receiver supply pins if not used.
