The Type 555 chip must be one of
the most popular ICs used in electronics.
Here it is used as a vco (voltage
controlled oscillator). The circuit
depends on the fact that a control
voltage on the CV input can vary the
internal divisor. The consequent shift
of the threshold causes an alteration
of the change-over points, which result
in a change in the oscillator
frequency.
