Dear Sirs,
I am using Eval board of AD3683 with TI data catcher TSW1400. Configuration: Bypass mode, 2wire connection, 18bit. The amplitude in the FFT spectrum is OK, but the corresponding frequency is twice higher than input frequency. It seems to me, even samples are skipped. Also the GUI shows me 4 channels, I expect 2 channels (NCO is bypassed, Decimation is bypassed, thus the data are real only). I assume the setting in ADC35xx is wrong, what shall I change?
