Hello,
For our application we need to rapidly change the NCO frequency (in a way to scan the frequency spectrum). The SPI command approach is slow for this.
In one of the forum posts there was a mention about how some GPIO pins can be used to switch the NCO to pre-determined frequencies.
I had already asked this question : https://e2e.ti.com/support/rf-microwave-group/rf-microwave/f/rf-microwave-forum/1285010/afe7900evm-nco-frequency-configuration
However I did not receive an answer for my follow up query. We need to switch across multiple frequency bands (not just 2 bands).
Please advise,
