I'm sorry about my poor english skill.

I'm user of AD9910.

I want to fast frequency sweeping.


I read datasheet, then I learned about DRG(Digital Ramp Generator) and RAM mode.

They seems so fast enough but I wonder something about that.

I want to control frequency sweep by external pin(etc, I/O Update and so on...) pulse.


About RAM mode,

I/O Update pin acts like trigger signal, then 1024 word go to DDS core automatically.


Could I control that each frequency output by external hardware pin?
