Can anyone suggest me about the unused RF pins of the AD9361 to be connected to ground or to 1.3V....
ADFMCOMMS3 schematic shows that the unused RF pins are grounded but the datasheet recommendation is to connect it to 1.3V.
Page no 16 the datasheet.
A7, A8 TX2A_N, TX2A_P Transmit Channel 2 Differential Output A. Tie unused pins to 1.3 V.
A9, A10 TX2B_N, TX2B_P Transmit Channel 2 Differential Output B. Tie unused pins to 1.3 V.
