Interpretation of VCXO VG7050CDN oscillator

二、 Characteristics of VCXO VG7050CDN

1. High precision frequency regulation

The VCXO VG7050CDN has excellent frequency regulation accuracy. It can achieve small frequency changes over a wide frequency range, meeting the high requirements for frequency accuracy in applications. For example, in frequency synthesizers in communication systems, precise frequency adjustment is required to switch between different frequency bands, and VG7050CDN can provide stable and accurate frequency control.

2. Low phase noise

Phase noise is an important indicator for measuring the performance of an oscillator, which reflects the spectral purity of the oscillator output signal. VG7050CDN has extremely low phase noise, which means that its output clock signal has higher quality and stability. In applications such as radio frequency communication and satellite navigation that require strict signal quality, low phase noise can effectively reduce signal distortion and interference, and improve system performance and reliability.

3. Fast frequency response

This oscillator can quickly respond to changes in control voltage and achieve fast frequency switching. This feature is very important in systems that require real-time frequency adjustment, such as adaptive communication systems, frequency hopping communication, etc.

4. Good temperature stability

Despite being a variable crystal oscillator, VG7050CDN can maintain relatively stable performance in different temperature environments. Through internal temperature compensation circuits and optimized design, it can maintain frequency stability over a wide temperature range and reduce frequency drift caused by temperature changes.

5. Small size packaging

Adopting a compact 7.0mm x 5.0mm package is advantageous for layout and integration on space constrained circuit boards. This makes it suitable for miniaturized, portable electronic devices such as smartphones, tablets, etc.

三、 Working principle

The core of VCXO VG7050CDN is a crystal resonator and a varactor diode. The crystal resonator determines the fundamental frequency of the oscillator, while the varactor diode responds to changes in control voltage by altering its capacitance value.

When the control voltage is applied to the varactor diode, its capacitance value changes, thereby altering the equivalent capacitance and inductance of the crystal resonator, leading to a change in the resonant frequency. Through carefully designed feedback circuits and amplifiers, the oscillator can operate stably at new frequencies.
