音解码器 Tone Decoder
DESCRIPON
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.
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
APPLICATIONS
• Touch Tone Decoding
• Precision Oscillator
• Frequency Monitoring and Control
• Wide Band FSK Demodulation
• Ultrasonic Controls
• Carrier Current Remote Controls
• Communications Paging Decoders
