Question of ADF4355 Register Settings

Dear Analog Devices,

 

I have a couple of questions on certain register settings of the ADF4355, ahead of our first prototype release. We will be using this device in a wide band application, producing LO frequencies from 600 - 6000MHz. We will set a default LO of 6000MHz (upon initialisation), while software algorithms will determine how the output frequency will vary.

 

Regarding Register 4 and, having read the datasheet, I am not quite clear on the preferred settings of:

 

- Double Buffer: Enabled or Disabled? Does it matter?

- CP 3-State: Enabled or Disabled?

- Counter Reset: Is it preferable to have it enabled or disabled?

 

I would be grateful for your assistance.

 

Thanks a lot,

 

Michael
