Tone decoder/phase-locked loop

NE/SE567

DESCRIPTION

PIN CONFIGURATIONS

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

components.
