Question about the relationship between DEV_CLK_IN and IQrate?

Modified AD9528_Evaluation_Board and input REF CLK = 98.304 MHz.
(C407 / C409 implementation, R414 / C408 removal)


I set AD9371 as below.
 DEV_CLK_IN = 98.304MHz
 IQrate     = 49.152MHz


The following error occurred.


  Mykonos pllStatus = 0x1L
  MCS Status =  0xbL
  System.Exception: Error Programming ARM: ERROR:452, ARM system problem has been detected.

Do you know the cause?


I do not know the setting of the value of Mykonos.init_clocks and the value of Mykonos.init_rxProfiles.
Could you tell me how to set it when IQrate = 49.152 MHz?


Link.Mykonos.init_clocks(98304, 7864320,Link.Mykonos.VCODIV.VCODIV_2, 4)
Link.Mykonos.init_rxProfiles(1, 2, 2, 5, 1, 1, 49152, 10000000, 10000)
Link.Mykonos.init_txProfiles(1, Mykonos.DACDIV.DACDIV_2p5, 2, 2, 1, 1, 49152, 10000000, 100000000, 100000, 100000)


I attach python script. : AD9528 setting   : AD9371 setting
