(6) Notes on VCO design
The VCO must be designed so that the VCO oscillation does not stop if the control voltage (Vtune) becomes 0 V. If it is
possible for this oscillator to stop, use the charge pump control data (DLC) to forcible set Vtune to VCC temporarily to
prevent the PLL circuit from deadlocking. (This function is called a deadlock clear circuit.)
