Tone Decoder
LM567/LM567C
Tone Decoder
General DescriptionThe LM567 and LM567Care general purpose tone decoders
designedto providea saturated transistor switchto ground
whenan input signalis present within the passband. The
circuit consistsofanI andQ detector drivenbya voltage
controlled oscillator which determinesthe center frequency the decoder. External components are usedto indepen-
dentlyset center frequency, bandwidth and output delay.
Features20to1 frequency range withan external resistor Logic compatible output with 100 mA current sinking
capability Bandwidth adjustable from0to 14% High rejectionofoutof band signals and noise Immunityto false signals Highly stable center frequency Center frequency adjustable from 0.01Hzto 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
