NJM567 Datasheet (New Japan Radio) - TONE DECODER/PHASE LOCKED LOOP

NJM567, TONE DECODER/PHASE LOCKED LOOP

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.
