The LM567 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 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 center frequency, bandwidth and output delay.
Features Include:
20 to 1 frequency range with an external resistor
Logic compatible output with 100 mA current sinking capability
Bandwidth adjustable from 0 to 14%
High rejection of out of band signals and noise
Immunity to false signals
Highly stable center frequency
Centre frequency adjustable from 0.01 Hz to 500 kHz
Applications
Touch tone decoding
Precision oscillator
Frequency monitoring and control
Wide band FSK demodulation
Ultrasonic controls
Carrier current remote controls
Communications paging decoders
