DEARS.

We are testing with DAC38J84EVM with TSW14J56EVM

How do I set the NCO of a DAC38J84?

I'd like you to give me an example.

Thank you.

    Hi Henry,

    here is an example for 1228.8MSPS of DAC sample rate, with 307.4MHz of NCO mixing rate.

    You will need to enable the NCO accumulator and mixers. Update the registers with the FNCO and Fdac, and then synchronize the NCO with SIF_SYNC (if this is the sync source that you would like to use).
