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
components.
