Henry, Per the JESD204B standard, the value of F * K must be greater than 17 and less than 1024. Currently you have this as 8 since your LMF setting is 882 and K = 4. You must change your K value to a number greater than 8. I suggest you set this to 10 and use a SYSREF frequency of 22.66666MHz or a integer divided for this value. Regards, Jim
