LM567CMX

◇ 产品简介 ◇

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 Iand 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.

◇ 功能特性 ◇

●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

◇ 应用范围 ◇

●Touch tone decoding
●Precision oscillator
●Frequency monitoring and control
●Wide band FSK demodulation
