TONE DECODER
Description
The S567 is general purpose tone decoders designed to provide a saturated transistor
switch to ground when an input signal is present within the passband.
Features
• Logic compatible output with 100mA current sinking capability
• 20 to 1 frequency range with an external resistor
• 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 0.01Hz to 500KHz
Applications

1. Oscillator with Quadrature Output
2. Oscillator with Double Frequency Output
3. Precision Oscillator to switch 100mA Loads
Electrical Characteristic Curves
1. ICC vs Vcc
The center frequency of the tone decoder is
equal to the free running frequency of the VCO.
2. BW by
- fO fo = 1/(1.1R1C1)
This is given
The bandwidth of the filter may be found from
the approximation
B.W =1070(√VIN / f0C2) in % of fO
Where
VIN = Input voltage(Volts
rms
), VIN≤200mV
C2 = Capacitance at pin2(uF)
