ADRV9364-Z7020 support/clarification needed - bad documentation and links

We have bought a ADRV9364-Z7020 + the PicoZed BoB

I have spent close to two hours trying to ascertain just few basic things. I'm no longer sure if I still have the correct info and so am posting here to clarify.

1)  My very simple question is are the RxA and B and TxA and B two independent Rx and Tx input/outputs respectively?

2) Are they truly broadband over the entire 6 GHz range? I'm inclined to think yes because based on the schematic the only balun is a minicircuits transformer that seems to cover the entire range. But on some link I also read that this is tuned to 2.5 GHz and this confused me. Can you confirm that I can indeed tune the Rx to receive over the entire 6 GHz range?

I have some serious complaints on the documentation of this part...

On this site it is claimed that the ADRV9364-Z7020 is schematically and HDL similar to AD-FMCOMMS4-EBZ. Great, because of this there's no dedicated functional block diagram or description for the this specific part. At best there is a link to ADRV9361-Z7035 which seems to have more Rx/Tx and is not helpful in trying to understand the ADRV9364-Z7020. Fine I then goto this FMCOMMS4-EBZ link > Functional Overview. I find that the functional overview image is actually for the AD-FMCOMMS2-EBZ with an AD9361 (are you serious right now?).

So I still have no clear picture about the ADRV9364-Z7020. Furthermore the FMCOMMS4-EBZ seems to be a 1 Rx and 1 Tx card which is NOT SIMILAR to the ADRV9364-Z7020 which clearly is a 2 Rx, 2 Tx card. Additionally the FMCOMMS4-EBZ seems to have one channel tuned to 2. 5 GHz which is again in NOT WAY SIMILAR to the ADRV9364-Z7020. This is just extremely misleading and shoddy documentation. Why can you not simply have some functional documentation dedicated to the ADRV9364-Z7020 if it's clearly not like the ADRV9361-Z7035 and most certainly not like the FMCOMMS4-EBZ. I'm not afraid of reading electrical schematics but some functional description should be easily available to get a quick gist of the product.

Lastly almost every link I click on I get routed to info about the ADRV9361-Z7035 which is NOT THE PART I BOUGHT. Should I simply have bought this part instead and saved myself this frustration?

And I haven't even gotten to the back-end builds and am not very anxious about what bad documentation related problems I'll face at that end.

    The 9364 has three Rx and two Tx channels but these are multiplexed. Hence the 1x1 nomenclature. However the ADRV9364-Z7020 still has two Rx and Tx channels broken out to the U

    AD9364 chip…

  • Since my last post I I have managed to glean the following and am recording here for anyone else in the future who runs into similar furstrations...

    The 9364 has three Rx and two Tx channels but these are multiplexed. Hence the 1x1 nomenclature. However the ADRV9364-Z7020 still has two Rx and Tx channels broken out to the UF.L connectors so in principle there's some way to time multiplex Tx and Rx (I don't really need this functionality but just recording my learnings here) - so once again very confusing to equate this part to the FMCOMMS4-EBZ.

    Still no luck with ADRV9364-Z7020 specific functional documentation - but I will make do with schematic and pinout table for now.

    Going through the same exercise for the breakout board that I bought i.e. the ADRV1CRR-BOB - and similar frustrating saga.

    The only way to get a 'Quick start guide' for this carrier board along with schematics is to google. And specifically one has to google for PZSDRCC-BRK (which is the label on the physical board). None of these guides are available on either Avnet or on AD sites (the AD wiki does atleast contain the schematics and BoB - thank my stars) . Otherwise All the links pointing to Avnet from AD simply goto the current PicoZed offerings which do not include this BOB - I'd consider these links trash at this point.

    AD9364 chip has only one TX and RX chain enabled, it is a 1R1R chip. AD9361 is a 2T2R chip. W donot have three RX channels for any of the AD936X chips..

    RXA,B,C all three ports uses the same RX path. Refer to the below snippet from datasheet:
