I am just studiung about your V-F converter AD7741.
Do you have a good solution over 3MHz output to use your AD7741 or another V-F converter?
On your datasheet AD7741 can output 2.7648MHz.
(This come from max. output freq=0.45x fCLKIN. So I put fCLK max=6.144MHz.)
So I need more high frequency output.
Please give me your good comment.
