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,
