TONE DECODER/PHASE LOCKED LOOP
Description
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.
