NE567 Datasheet | Philipss

Philips Semiconductors Linear Products Product specification Tone decoder/phase-locked loop NE/SE567 DESCRIPTION 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. The bandwidth center frequency and output delay are independently determined by means of four external ponents.
