I am using AD9129 at 2457.6 MHz. I get PLL and DLL lock properly. My fifo levels are stable at following values:
address 0x13 is at 0x01
address 0x14 is at 0x01
address 0x15 is at 0x03
address 0x16 is at 0x03.
I am using SED feature of the IC and I am getting no errors at all. My DCI line is another data line, specifically an LVDS line. However when I read register 0x0E I read 0x87 which means data is sampled on incorrect phase.
Why am I getting this error when everything looks just fine?
Secondly, can you please elaborate on what data is sampled on incorrect phase mean and how the IC knows about it?
