Do I need to connect the CEN pin of the HMC703LP4E to 3.3V?

I am using the HMC703LP4E. The current CEN pin is not connected at all.

In other words, the CEN pin is floating.
If nothing is connected to the CEN pin, I wonder if the HMC703LP4E can malfunction.

I wonder if it is ok to connect the CEN pin to the 3.3V power line of the HMC703LP4E.

For example, connecting 21 pin(CEN) to 23pin(VDDPD).


I also wonder what exactly the role of the CEN pin is and wonder if the hardware is implemented, such as an internal pullup or pulldown.
