Hi Enrico,
Let me start with your last question and I’ll move on:
In your last reply, on e2e, you wrote " J10 as well as J1 are meant to be input clock and not output clock in CW mode." Did you write J1 in part of J9? J1 is correct? The input clock are J10 and J9. It's correct?
Yes, you’re definitely right – sorry for the error while replying. I meant J10 and J9 since J1 is not an input clock.
We need to get the digital data output , from I/Q output ,and to process them. Normally these data are available as analog data/signals? Can you give us advices or tips on how to acquire and process them?
Keeping in mind that the CW outputs are analog and that you can’t use the AFE5809 ADC to digitize them since the frequency is in the audio range and it can’t be processed by the AFE5809 chip you need an external Analog to Digital Converter doing the job. Additionally, as I don’t think you can get enough power out of J12 and J13, you might need to amplify the signal before feeding it into the ADC. To this end, you can use our EVM CW circuit as a reference design – there’s an amplifier onboard you could eventually use.
Are there any constraint for the 8MHz external oscillator characteristics/signal?
Using the 8MHz output from CDCM clock device would be low power and you probably need to amplify that as well.
Hope it helps. Just let me know should you need any further support.

Fabio
