DESCRIPTION
The LM567 and LM567C are general purpose tone
decoders designed to provide a saturated transistor
switch to ground when an input signal is present
within the passband. The circuit consists of an I and
Q detector driven by a voltage controlled oscillator
which determines the center frequency of the
decoder. External components are used to
independently set center frequency, bandwidth and
output delay.
