New Japan Radio Co.,Ltd. www.njr.com NJM567 TONE DECODER / PHASE LOCKED LOOP GENERAL DESCRIPTION PACKAGE OUTLINE 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.
