A voltage-controlled oscillator (VCO) is an electronic oscillator whose oscillation frequency is controlled by a voltage input. The applied input voltage determines the instantaneous oscillation frequency.

Analog Devices offers a broad portfolio of voltage controlled oscillators (VCO) with excellent phase noise performance, options for wideband, and multiple choices including VCOs with output drivers and VCOs with single output to meet small size and low power requirements.

Wide selection of models from spot frequency and narrow band to medium and wide bandwidths up to 1.5 octaves with low phase noise, linear tuning, dual outputs, 5V tuning for PLLs and more!

Jan 26, 2021 · The VCO has an output power level of -3 dBm into 50 Ω with phase noise of -101 dBc/Hz typical at 100 kHz offset. The control voltage range is 0.4 to 2.4 volts, and load pulling is typically 0.75 MHz, pk-pk. Power supply pushing is 280 kHz/volt (typical).

A voltage-controlled oscillator (VCO) is an electronic oscillator whose oscillation frequency is controlled by a voltage input. The applied input voltage determines the instantaneous oscillation frequency. Consequently, a VCO can be used for frequency modulation (FM) or phase modulation (PM) by applying a modulating signal to the control input.

VCO Oscillators are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for VCO Oscillators.

Explore different VCO types (RC, LC, crystal, etc.), their characteristics, and their applications. Learn how VCOs enable precise frequency control.

This page describes the basics and function of a VCO (Voltage Controlled Oscillator). Oscillators whose frequencies are controlled using an external input DC voltage are referred to as VCOs.

Mar 28, 2025 · A Voltage Controlled Oscillator (VCO) operates as an electronic generation device that produces oscillating signals through voltage control. The fundamental operation of a VCO entails transforming direct current voltage into alternative current signals with frequency values that relate to the applied voltage amounts.
