I was wanting to find out if the AD9364 can be used in a pin-to-pin compatible configuration with the AD9361.
Initial layout was targeted using the AD9361 but we are now going with the AD9364. However with the AD9364 pins A1, A2 and
few others are VSSA (GND pins) as opposed to signal pins on AD9361. The data sheet for the AD9364 wants them to be connected to Ground.
Is this grounding done precautionarily or is it functionally necessary?
Internally for the AD9364 – how are these pins (A1, A2 etc.) connected/used? Are they wire bonded? Are they left open? or Are grounded internally? Are they active ground paths?
