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.
