SE567 Datasheet (Philips) - Tone decoder/phase-locked loop

SE567, Tone decoder/phase-locked loop

The NE/SE567 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.
