9.1 Overview

The LM567C is a general purpose tone decoder. The circuit consists of I and Q detectors driven by a voltage controlled oscillator which determines the center frequency of the decoder. This device is designed to provide a transistor switch to ground output when the input signal frequency matches the center frequency pass band. Center frequency is set by an external timing circuit composed by a capacitor and a resistor. Bandwidth and output delay are set by external capacitors.
