VCXOs (Voltage controlled crystal oscillators)
A voltage-controlled oscillator or VCO is an electronic oscillator specially designed to be controlled in fluctuation frequency by a voltage input. It includes a varactor diode and linked circuitry allows the frequency to change. It offers Connor-Winfield's extensive resonator production uses.
Manufacturers of the leading brands of VCXOs are listed with us, who have been cultivating the benefits of being connected to the vast network of buyers and sellers of the VCXOs. Our online catalog of VCXOs consists of thousands of VCXOs supplier and distributors who work together to enlarge the market of these manufacturers. The manufacturers are able to present their exclusive ranges and features of their product line.
Distributors, suppliers and representatives of VCXOs are provided the opportunity to spread their market through wide channels of internet marketing as well as develop relations with leading manufacturers of the industry.

Every product design has to be tested in order to determine its actual standards of functioning. Any glitches are to be avoided in order to the most superior and reliable product. Design engineers have to test the product and test its efficiency at various temperature, pressure, voltage level etc. Temperature and voltage are two such factors which led to the development of crystal oscillators like TCXOs and VCXOs.
An engineer uses voltage-controlled crystal oscillator (VCXO) when the frequency of operation needs to be adjusted only finely. Thus there are two reasons for using a VCXO:
- To adjust the output frequency to match (or perhaps be some exact multiple of) an accurate external reference.
- Where the oscillator drives equipment that may generate radio-frequency interference, adding a varying voltage to its control input can disperse the interference spectrum to make it less objectionable.
Until and unless engineers find the right kind of VXCO for his design he can never estimate and test the actual potential of the prototype. Engineers spent hours and even days searching for the VCXO they require. But now through us, engineers have the solution at their bay. All the leading brands of voltage controlled crystal oscillators are available online through our website, this offer one-stop solution for the engineers to transform their designs into prototypes.
