Hi there!!

I am going to use LMX2571 to make 100MHz from the source (10MHz).

And I will use the internal VCO. And I don't need Fast Lock function.

Since I only need 100MHz output.

In this case, do I leave FLOUT1, FLOUT2  open like…

In addition…

We use the LMX2571 in a design to generate 190 MHz LO for a receiver downconverter.
