I am using AD9789 interfaced with AD9516.
Schematic is almost similar to Evaluation Board AD9789-EBZ
We are using Single Channel, 32 bit Access, 16 Bit Data, Complex mode ,
Fdac frequency is 2.340Ghz
Centre Frequency is 767.143Mhz
Calculated FTW is 0x3E7F4D
Calculated BPF centre Frequency (FC) is 0x53E3
SUM SCALE is 0x1d
input Scalar is 0x40
Ch 0 Gain register 0xC5
Desired signal Amplitude is very high as we expected.
however, there are spurious signal comming at multiple of 16Mhz from centre frequency,
We checked Parity and Satuaration counter but there was no issue there.
We are like stuck for 1 month .
Any ideas, suggestion are welcome.
