My understanding is that these two parts are pin to pin replaceable if only 1 x 1 TX/RX is required. Now if I layout my PCB for AD9361 then can I use AD9364 on that same PCB (Or vice versa)? For example, pin A1, A2 are GND on AD9364, but RX signal path on AD9361. There are more pins like it. Please shed some light into this. Thank You for support.
