■ TEST CIRCUIT
NJM2228
(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 stray capacitance of P.C
board, socket and others.
(note 3): The NJM2228 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.
