Frequency divider not working issue

Question

I want to use AD9547 to output two clocks of 150M and 50M. This is my relevant configuration. I have connected a 1GHz crystal oscillator externally, and I observed that DACOUT outputs a signal of 125MHz. However, when it is given to CLKIN, OUT0/1 does not output. Is it because my register is not configured correctly?

HI, 
 next time just send me the stp file you created. Do you have an evaluation board on which you are downloading this configuration? 
 I see two problems: First, you need to set up a profile for the AD9547 to work. Then, to generate outputs, you should execute a Sync operation (press Synchronize Distribution button in the Clock Distribution Window). See page 7 in the UG-639 eval board manual. 
 Why do you use the AD9547? Use instead one of the AD9545 family of IC (AD9545/44/43/42) which is a much newer architecture and easy to use.

HI, I'm sorry to say, but the stp file you uploaded did not load correctly. The file should be a simple ASCII file and yours looks like this: I do not have an AD9547 evaluation board, so I used an AD9548 one. I was able to configure it and obtain the output frequencies you want. Fullscreen AD9547_setup.stp.txt Download ;Header contains information about the setup file and revision

your situation: 1GHz system clock input, OUT0=150MHz LVDS, OUT1=50 MHz CMOS based on the experience using the AD9548. It should work. I used REFA=10MHz, 3dBm from a signal generator. If you need to use a different one, change the profile. Do not forget to generate a reference acquisition as part of the initialization sequence. See section Device register programming at page 24, rev G data sheet Petre
