My customer encounted a spurious signal that was multiplied by 30.72MHz in the tx path of AD9361.
The customer found that the spurious signal level was changed with LVDS amplitude control(0x03C [D2:D0]).
She considers that the register 0x03C[D2:D0] is only the LVDS amplitude contol of RX path.
Is it right ?
Could you please explain why the above symptom appear ?
Thanks a lot.
