Questions about the sysref input in board ZCU102-FMCOMMS8

Category: Hardware
Product Number: 0

I downloaded the hdl project of the offical version of board FMCOMMS8-ZCU102.And I noticed that the sysref_c connect with obs_jesd and the later IP like OBS_tpl. I wonder why design like this?Is RX data from adrv9009_c still transfer by rx_tpl?

And I tried to struct a block design like this FMCOMMS8-ZCU102 structure in Project ADRV9009-ZC706,however,after I changed the IP setting,it reminds me a lot of errors like 【common[17-249]】,and I don't know what the errors mean.Could you give me some advice?Thank you very much.
