ADC12DJ3200: Bias of a certain period

Part Number: ADC12DJ3200

Tool/software:

Dear Technical Support Team,

When I checked the operation of this ADC, I input a synthesizer (sine wave),
As shown in the attached graph ③, there is a bias of a certain period of about 18 cycles for the resolution of 12-bit ADC.
I connected this synthesizer to another measuring instrument (oscilloscope), but this symptom did not occur.

Is there any cause of this symptom or any register that can correct it?

For reference (See attached file)
