Dear Team,

We are trying to achieve the 4-channel synchronization of ADRV9009 but we are unable to achieve that. we followed the sequence mentioned in the datasheet and the recommendations provided by the ADI experts in the forum but nothing helped .Our experiment results are documented and I am attaching the document, please go through that to know what we have done and guide us to achieve the 4 channel synchronization.

Thanks in Advance DOCX

Are you connecting two boards on a single zcu102 FPGA? can you paste the steup diagram that you are following? Hope you are enabling RFPLL phase sync init and track cal and the MCS.

yes,we are connecting two boards on a single FPGA board .

Yes, we are enabling RFPLL phase sync init and track cal and the MCS.

RE: ZCU102 with two ADRV9009 issues => thread where you guided us to initialize the setup

Thank you

Can you try with external LO , use the same LO source for both the boards, to make sure that the phase measurement setup or procedure is correct?

Also, is it correct that you are reconfiguring or re-booting the board between tone1 and tone2 phase difference measurement between RX1 and RX3 ? Just to confirm your measurement, if you do not reboot, then the phase difference for tone1 and tone2 is same?
