Description

Explore the world of signal generation with this voltage-controlled oscillator (VCO) from Onsemi. A VCO is an electronic circuit that can produce a continuous output signal at a frequency that can be controlled by an applied voltage. This allows for precise adjustments to the output frequency, making VCOs essential components in various applications such as:

• Frequency modulation (FM) synthesis: VCOs are fundamental building blocks in FM synthesizers, which are used to generate radio waves for FM radio broadcasting and other wireless communication applications.
• Voltage-controlled filters: When combined with voltage-controlled filters (VCFs), VCOs can create tunable electronic sound effects, making them popular components in synthesizers and other audio equipment.
• Phase-locked loops (PLLs): VCOs play a crucial role in phase-locked loops (PLLs), which are circuits used for frequency synchronization, signal multiplication, and demodulation.

Key features of voltage-controlled oscillators (VCOs):

• Output frequency varies in relation to a control voltage
• Wide range of frequency outputs (depending on the specific VCO)
• Used in various electronic applications such as FM synthesis, voltage-controlled filters, and phase-locked loops
