Tone Decoder 		Click link to Download

Features
•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
•Center frequency adjustable from 0.01 Hz to 500 kHz

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.

Applications
•Touch tone decoding
•Precision oscillator
•Frequency monitoring and control
•Wide band FSK demodulation
•Ultrasonic controls
•Carrier current remote controls
•Communications paging decoders

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
