Product Summary

The LM567CN is a general purpose tone decoder, designed to provide a saturated transistor switch to ground when an input signal is present within the passband. The LM567CN 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. The applications of the LM567CN include Touch tone decoding, Precision oscillator, Frequency monitoring and control, Wide band FSK demodulation, Ultrasonic controls, Carrier current remote controls, Communications paging decoders.
