hi.I have an application of AD9915.In my application,I use serial mode.I use these signals:master reset,I/O_update,SDIO,SCLK,CS.I didn't use the signal sync_in.I want to know that whether this configure is correct or not.

I have configured the F[3:0] as 0001,PS[2:0] as 000,my refclk input from signal generator,it's frequency is 2.5GHz,amplitude is 0dBm.I need the AD9915 output the frequency is 200MHz to 300MHz.But now these is no any signal at the output pin.I want to know the reason.Thanks.
