This is David from CAST Beijing. I have a quesiton about AD9835.
How to synchronize two AD9835s? I checked AN-587, but It's for AD9850/1 which have FQ_UD pin.For AD9835, it haven't FQ_UD, then how to synchronize two AD9835s?
The AD9835 does not have the Reset pin required so you will need to look at either the AD9834, AD9830 or AD9831. FQ_UP has the same functionality as the FSYNC pin.
