AD2S1210 Resolver-to-digital Serial output data problems

I am currently using the AD2S1210 in order to read a Tamagawa TS2640N441E26 resolver, usign the SPI port to get position and speed data.


Data seems to be OK in some positions, but I am getting strange values around some specific angles, separed by 45 deg (image attached). I am having the same problem at all possible resolution configurations.


Has anybody encoutered the same problem?


Best regards,
