BLOCK DIAGRAM & EXTERNAL COMPONENTS
There is stray capacity assembled on PC board, and so select Rx, Cx to the value which pin 2 voltage (search voltage
at VCC locked) becomes about 2V. Cx>4pF, Rx>2.7kΩ

TEST CIRCUIT
(note 1): Rx, Cx accuracy: less than ±1%
(note 2): Cx is not considered pin 5 stray capacitance. VCO free-run frequency is affected by stay capacitance of PC
board, socket and others.
(note 3): The NJM2240 is produced by high frequency wafer process and some of pin may be weak against surge
voltage.
(note 4): Pin 2 filter must be connected to ground.
