ADF4360-7 vtune


I am currently using the ADF4360-7 as a programable signal source.

Is it possible to use the ADF4360-7 first to specify the frequency range by programming the device and afterwards as a VCO in a feed back loop externally modifying vtune?

Is this a normal operation mode?

How can the external control voltage be connected to vtune (pin 7).

In the current design vtune is connected to CP by a third order filter calculated by the software.

Do you perhaps have a application example for using the ADF4360 as a Integrated synthesizer and at the same time as a VCO?

Since I am new in this field the answer might by very simple.

Thanks a lot for your Help
