VCXO
Introduction
A VCXO (Voltage Controlled Crystal Oscillator) is a crystal controlled oscillator
where the frequency changes in direct proportion to the application of a control
voltage. In all VCXO's the type of modulator employed is a varactor diode. The
varactor diode is a semiconductor device that is designed to act as a variable
capacitor when a voltage is applied to it. When used in series with a crystal,
changing the control voltage causes the diode capacitance to change. This change
in capacitance causes the total crystal load change and subsequently causes
a change in crystal frequency. This change in frequency is known as deviation.
As new types and/or new ranges of oscillators are developed HM International is continuously
involved in custom design. Should you have a requirement our team of engineers
will be pleased to discuss your requirement with you.
