Voltage Controlled Crystal Oscillator (VCXO) VXA-01A Series
**Overview** In addition to the functions of a standard fixed crystal oscillator, this crystal oscillator includes a varicap diode and surrounding circuitry, allowing the frequency to be varied by the voltage applied to the varicap diode. For a VCXO, it is necessary to specify several unique specifications in addition to those of a standard fixed crystal oscillator. Generally, these include control voltage, frequency variable range, and slope, and if further specification is needed, linearity (or control sensitivity), input impedance, and input modulation frequency, among others.

Company information
We supply high-frequency crystal oscillators that achieve stable oscillation and low phase noise at high frequency bands without the need for precise processing of crystals (such as etching) through our unique frequency multiplication circuit technology and low harmonic distortion removal technology. 【Main Products】 ■ Crystal Oscillators These are packages that combine crystal resonators and circuits into one unit. They include SPXO, which simply outputs frequency, VCXO, which allows frequency to be varied by external voltage, and TCXO, which has an added temperature compensation circuit. ■ Crystal Resonators Crystal resonators oscillate by attaching metal electrodes to a crystal wafer and sealing it in an airtight manner, allowing it to be mounted on an oscillation circuit. ■ Various Components for Oscillators We handle various components for oscillators. Since July 2014, "Naka and Company, Inc." has become a 100% subsidiary of "Jell System, Inc." and a member of the Jell Group. Naka and Company will continue to strive to be of service to everyone, and we ask for your continued support and cooperation.
