i have an issue about AD9850.
theory: we can use the output of phase register and frequency control word to input sinusoid table to search
In real: i wonder how to use C code to search in sinusoid table.
The AD9850 (in fact, the entire high speed [>75GSPS] DDS portfolio) does not use a sine look up table for angle to amplitude conversion, it uses a proprietary algorithm, so there is no table on which to do a search. I do not believe you can accomplish what you want with anything in this portfolio.
