description

The 'S124 features two Independent voltage-

controlled oscilllators {VCO) in a single monalithic

chip. The output frequency of each VCO is established

by an external capacitor in combination with two

voltage-sensitive inputs, one for frequency range and

one for frequency control. These inputs can be used

to vary the output frequency as shown under typical

characteristcs. These highly stable oscillators can be

set to operate at any frequency typically between

0.12 hertz and 85 megahertz. '
