CVCSO-914-245.760

Introduction to Oscillators

An oscillator is an electrical circuit that produces a periodic signal such as sine wave, square wave or sawtooth wave. Oscillators are used in many electronic applications such as in amplifier applications, transmitter and receiver applications, and for the generation of timing signals. They are also used to generate signals for use in automatic control systems.

CVCSO-914-245.760 Application Field and Working Principle

The CVCSO-914-245.760 is a Voltage Controlled Crystal Oscillator (VCXO) that operates at a frequency of 914.245.760 MHz. It is widely used in SONET and SDH applications and the primary purpose is to provide a reliable timing signal in these communications systems. It is also used in other applications requiring stable and precise timing such as in microwave and radio applications.

The CVCSO-914-245.760 uses a quartz crystal as its resonance element and is controlled by a voltage input. It consists of an amplifier stage, a voltage controlled resistor, and a quartz crystal resonator. The amplifier provides gain, while the voltage controlled resistor allows the frequency to be controlled by an external voltage source. When an external voltage is applied to the CVCSO-914-245.760, it will modify the frequency of the oscillator, resulting in a frequency shift. The frequency of the oscillator is also affected by temperature changes, and this can be compensated for with a temperature compensator.

The CVCSO-914-245.760 is mainly used for timing and synchronous applications in SONET and SDH systems. It is also used in frequency synthesizers and other frequency control applications, due to its excellent stability and accuracy. The frequency stability of the oscillator is typically ±25 ppm over a temperature range of 0-50°C.

In conclusion, the CVCSO-914-245.760 is a high accuracy, voltage-controlled crystal oscillator that is mainly used in SONET and SDH applications. It has excellent frequency stability and accuracy, making it suitable for applications requiring precise timing signals.
