As the picture shows, it is a linear voltage-controlled oscillator circuit. A1 is the constant current power supply circuit used to improve C1, which ensure the linear relationship between output frequency and input controlled voltage. A2 is the sine wave output bumper. If inputting low frequency saw wave to the voltage controlled port, the circuit is changed to linear scan generator and if inputting the voltage of some signal into input port, the circuit outputs frequency-modulated wave.
