In our application we are using AD4113 PLL with ROS-1000C-319+ VCO for 1 GHz constant clock generation. The charge pump information from the datasheet says that varies from 2.5 V  to 23.5V(with rset=4.7Kohm) .The VCO required 2.9V to lock to the frequency. is the charge pump voltage can be incresed to the level required to the VCO by using active loop filter or only passive loop filter is enough for this application.

Can AD4113 can be used to the max.freq 1GHz or bettr to use less than 1 GHZ?
