DescriptionThe 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.Key Features20 to 1 Frequency Range With an External ResistorLogic Compatible Output With 100-mA Current Sinking CapabilityBandwidth Adjustable From 0 to 14%High Rejection of Out of Band Signals and NoiseImmunity to False SignalsHighly Stable Center FrequencyCenter Frequency Adjustable from 0.01 Hz to 500 kHz
