(1) TX4 is only applicable in the AWR294x variant with 4 transmitters i.e. AWR2944.
(2) For details, see Section 8.4.3
(3) Corner BGAs are VSS and redundant, meaning if they fail the device will still function.
(4) The VSSA BGAs around the launches are not redundant and are required for functionality.
