application  
Charge pump phase frequency detector output: the PLL loop  
filter is connected in shunt and close proximity to this pin. The  
PLL loop filter tuning control voltage should be routed to the  
external VCO varactor circuit using minimal trace lengths in  
complete isolation from all potential coupling sources.
