Hi,

If we set the Gain to 1.8V. Does it work? The gain will be 30dB? Thanks!

Hi, Jerry,

How's it going?

I believe setting GAIN to 1.8V will result in an undetermined state. Please tie it to the VDD voltage if you wish to get 30 dB of gain.

Let me know if you have any more questions.

Hi, Jerry,

I checked into this issue a little further, and I found some data that suggests 1.8V might be okay. So, if the customer has already built boards, it should be okay, but if they are still in the design phase, I'd recommend tying it to VDD to be compliant with the d/s.
