Description
NJM567 TONE DECODER / PHASE LOCKED LOOP * GENERAL .
The NJM567 tone and frequency decoder is a highly stable phase
locked loop with synchronous AM lock detection and power output circuitry.
Features
* Operating Voltage
(4.75V to 9.0V)
* Wide frequency range
(0.01Hz to 500kHz)
* High stability of center frequency
* Independently controllable bandwidth
(up to 14 percent)
* High out-band signal and noise rejection
* Logic-compatible output with 100mA current sinkin
Applications
* the following three-step procedure will
be sufficient for choosing the external components R1, C1 C2 and C3.
