The LM567CN is general purpose tone decoder 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 centre frequency of the decoder. External components are used to independently set centre frequency, bandwidth and output delay
