Other Parts Discussed in Thread: ADC3683,
For our application we would like to use the ADC3683 in 0p5 wire mode. I tried to set the software for the EvalBrd accordingly using real decimation with a decimation factor of 4 according to table 8-5 from the datasheet on page 36. The calalculated DCLKIN frequency for a sampling rate of 65 MSPS was 73.125 MHz instead of the 292.5 MHz stated in the datasheet.
Please advise on how to set the software to the parameters from the datasheet.
Furthermore I noticed that only 2 wire mode is supported by the onboard clock generator IC. Is there any possibility to use the clock generator IC of the EvalBrd for 0p5 wire mode as well e.g. by replacing the quarz oscillator or feeding an external clock signal into the secref input? If so, how do I tell the software to set the clock generator IC correctly with the changed quarz or by using the secref input?
Thank you in advance!
