Hello,

 

We have received a question anout how to trigger of AD9914 DDS output.

Can be DDS output triggered by I/O_update assert?

 

When we asserted I/O_update, DDS is outputed after approximately 150nsec. But it differed around 10nsec. Is this correct operation?

 

The coustomer would like to reduce it to maximu 2nsec. Can we trigger DDS output to under 2nsec variation by I/O_update? If yes, how should we do?

 

 

Best regards,

Akira
