Hello,

I am using Ad9833 in my recent project but it gets failure i.e out put is not comming and goes to approx at 5V level,this thing happend many times.So kindly suggest.

I have put decoupling cap as well as tant cap on supply pin also having good layout.

Ya one thing is happening in my design is that, at power on Master clock is not comming and it takes time may be some time not...so is this the resion for problem of damage the chip.when output is not comming ,the ressitance betweem +5v and gnd is about at 200 ohm.

 

Kindly suggest if any thing i could missed out.
