NJM567M loop equivalent, tone decoder/phase locked loop.
* Operating Voltage
(4.75V to 9.0V)
* Wide frequency range
(0.01Hz to 500kHz)
* High stability of center frequency
* Independently controllable band.
the following three-step procedure will
be sufficient for choosing the external components R1, C1 C2 and C3.

The NJM567 tone and frequency decoder is a highly stable phase
locked loop with synchronous AM lock detection and power output circuitry. Its primary function is to drive a load whenever a sustained frequency within its detection band is present at t.
