LM567/LM567C

Tone Decoder

n High rejection of out of band signals and noise

n Immunity to false signals

n Highly stable center frequency

General 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 cir-

cuit consists of an I and Q detector driven by a voltage con-

trolled oscillator which determines the center frequency of

the decoder. External components are used to indepen-

dently set center frequency, bandwidth and output delay.

n Center frequency adjustable from 0.01 Hz to 500 kHz

Applications

n Touch tone decoding

n Precision oscillator

n Frequency monitoring and control

n Wide band FSK demodulation

n Ultrasonic controls

n Carrier current remote controls

n Communications paging decoders

Features

n 20 to 1 frequency range with an external resistor

n Logic compatible output with 100 mA current sinking

capability

n Bandwidth adjustable from 0 to 14%
