AD9144

 

I am trying to set up the AD9144 DAC registers but there are some questions that I would like answered and I was hoping that someone in the community has had previous experience with the AD9144 DAC registers.

 

I will list the questions that I have.

 

Two questions that I have that are not part of the registers are:

 

  1. Is the input signal pins 5 and 6, SYSREF±, supposed to be at the same frequency as the input signal pins 2 and 3, CLK±? My clock oscillator is 2.8GHz.
  2. Can anyone tell me what I am supposed to utilize the SYNCOUT0+ and SYNCOUT0−, pins 23 and 24 for?

 

These questions have to deal with the registers.

 

I do not need all of the differential SERDIN inputs.  I only need one differential SERDIN input.

I also want to utilize a three wire interface.

 

Here are the registers I know I have to set up.

 

Register

0x000

0x12D

0x146

0x201

0x232

0x2A4

0x333

 

I feel that I am missing some registers that I need to set up.

 

Can anyone tell me what registers I need or do not need to set up the AD9144 DAC for my needs?
