Hi,I want to create a DDS Function Generator capable of producing Sine,Square,Triangle Waveforms upto 3Mhz.I want to use AD9834 as it produces all three functions.I also want to try and implement PSK and FSK using inbuilt PSELECT and FSELECT pins.I want to know if anyone has already done it and has a base circuit which I can work on.Thank You

AD9854 and AD9852 are very similar except the quadrature output for the second one.

success!

Oops I've confused AD9854 with AD9834....

I found a circuit for AD9834 but I am having trouble making a PCB from the Schematic in Eagle.This is due to certain constraints I have because of living in India. I have to make it Single Sided and using through hole components because.I will upload the schematic and can someone please make a board design for me.Thank You.

I know this is an old topic, but if you still need the board design. I made one sided smd design according to spec. here is te Eagle files...

BTW: does anybody have better explained controll interface for te circuit???
