Otava DTRX2 mmWave Radio Card for Xilinx RFSoC ZCU208 Evaluation Kit

Hi Michael,

I'm sorry for all of the confusion.

Please let me know which support email address you tried (and where you found it). I would like to get that corrected ASAP.

Our documentation for Getting Started is online @ Getting Started Guides for Avnet RFSoC Boards — mmw-docs v1.0 documentation

Thanks for pointing out that this is not linked on Otava or Avnet sites. I'll make sure that is fixed.

Our SW/FW design is a modified version of the Xilinx RF Data Converter Evaluation Tool (v2020.2) - download site

The modification is accomplished via TCL scripts for the Vivado project, and a several modifications to the PetaLinux BSP. The source code for these modifications is freely available. We are in the process of moving our private GitHub repo to public status so that the project can be cloned/forked/etc. Should be finished at the end of this month. If you need access sooner, please let me know.

Thanks & good luck!

Hi Matt !

Thanks for your reply ! Thanks for those two links, but with those I have been familiar with, already. I really was expecting something like:

- How is the Otava Card working in Detail (e.g. as Detailed as the Documentation of Xilinx for the Motherboard is, like register mapping, adresses, sepcs and so on) ?

-  What Libraries are used ?

- What Interface is used ?

- Which Applikation is used ?

- Where can i find more detailed schematics of the circuits and the according connectors/interfaces ?

BR,

Michael

Hi Michael,

The detailed datasheet would answer many of your questions. We first need to verify your kit order.

Please send your PO number or web receipt to rfinfo@avnet.com

Thanks!

Hi Matt,

i have sent the whole Confirmation Mail including the PO number to this mail address.

How to proceed ?

Thank you.

BR,Michael

Thank you Michael. Our team received your email and will respond with the DTRX2 datasheet today or tomorrow.

As others on this forum may wonder about the answer to your other questions, I'll respond here for posterity.

- How is the Otava Card working in Detail (e.g. as Detailed as the Documentation of Xilinx for the Motherboard is, like register mapping, adresses, sepcs and so on) ?

The full datasheet is not published on the web. We send it to customers who have purchased the Otava DTRX2 Card. Register mapping can be examined within the source code. See details in my earlier response for info on the source code repo.

-  What Libraries are used ?

The DTRX2 must be mated with the Xilinx ZCU208 RFSoC Evaluation Board. Our software & firmware for the ZCU208 builds upon the Xilinx reference design. See details in my earlier response.

- What Interface is used ?

Electrically and mechanically, we interface the ZCU208 to the Otava DTRX2 by way of the Xilinx RFMC 2.0 connector.

The digital control interface for the RF signal chain aboard the DTRX2 is accomplish via custom HDL IP module that converts SPI to the serial protocol required for the chips on the DTRX2. We also have SW running on the US+ processors to receive commands via TCP/IP and translate them to SPI commands for the HDL IP.

- Which Applikation is used ?

We provide the Avnet RFSoC Explorer application

- Where can i find more detailed schematics of the circuits and the according connectors/interfaces ?

The full datasheet is not published on the web. We send it to customers who have purchased the Otava DTRX2 Card.

Thanks,

Hi Matt,

up to now, no Information have been received. I have received a mail from Avnetsales though. They ask me for additional information, such as company name, company address, etc ...

Before i created the post in this forum, i sent a mail to Avnetsales, but got no answer. Now the question is, is this mail i received just the very delayed answer to my initial mail, or is this related to our conversation ?

BR,

Michael

Hi Michael,

Please check your inbox. I forwarded the documents.

Thanks,

Hi Matt,

I've replied to your mail. I'm not sure if this reply-mail have reached you yet. I wonder for some Buttons from the Avnet RFSoC Explorer 2.0 GUI, from which i can not find the corresponding API command-line command. Namely:

- The drop down menu and according button to select the ref clock source.

- The Button to update the PLL.

Also do you have any updates on the code repository ? Ive seen there a button to sync tiles in either TX or RX. Is it possible to sync an TX tile with an RX tile in some way, with the Avnet Explorer RFSoC Explorer 2.0 ?

Thanks!

BR,

Michael

Hi Michael,

Unfortunately I didn't see your email.

We've added an API call for updating the CLK104 LMK chip. That will go up on File Exchange in the next week.

Are you looking for an API to update the PLL on the DTRX2 card?

MTS is not yet implemented in API or GUI. Unfortunately I don't have a roadmap date for that feature yet.

Thanks,

/Matt

Hi Matt,

thanks fur the update. When i say "to update the PLL" i mean the following:

After changing this value in the GUI:

I need to push this button to take effect:

The command line command according to this first picture, i found in your API documentation:

Avnet_RFSoC_Explorer('DTRX2', <dtrx2_cmd>, <parameter>)

- TX_IF_signal_BW, parameter = TX signal bandwidth (MHz)

But I did not found with which command line command i can "Update PLL" as like the button in the second picture, for the BW setting to take effect. This is necessary for every signal where the BW differs from the default 50MHz, so i assume there is an according command line command ?

Thank you!

BR,

Michael
