NJM567
TONE DECODER / PHASE LOCKED LOOP
■ GENERAL DESCRIPTION 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 the self-biased input. The bandwidth cebter frequency, and output delay are independently determined by means of four external components.
