Oscillators

The ECX-H27CM-50.000 oscillator represents one type of oscillator technology from a heterogeneous field of oscillators. The technology category in question is termed “temperature-compensated crystal oscillator” technology, or “TCXO” for short.

A TCXO oscillator is defined as a specific type of oscillator that uses a quartz crystal as its core frequency control element. This type of oscillator is designed to compensate for fluctuations in the frequency over varying temperature conditions. This oscillator generally features temperature control technology and high stability requirements, and its applications range from timing and frequency control to radio reception. The ECX-H27CM-50.000 is an example of a “high-precision TCXO” with a very low temperature coefficient (typical value of 10 ppm/°C), and it is ideal for demanding applications where high performance is required in demanding environments.

The basic working principle of a TCXO oscillator is to measure the frequency generated by a quartz crystal and then automatically adjust the voltage applied to the crystal to compensate for variations in oscillation frequency due to temperature changes. The frequencies generated by the crystal are monitored by a temperature control circuit with a precision amplifier, and a voltage-controlled oscillator (VCO) is then used to make frequency adjustments in real time. This in turn allows for very precise frequency control and stability over temperature.

Applications of a TCXO oscillator are typically found in applications where performance and reliability are absolutely essential. Examples include equipment used in telecommunications, avionics, defense systems, navigation systems, and industrial control systems. This type of oscillator can also be used in high-precision laboratory measurements, and for the purpose of tuning and aligning radar systems.

The most important consideration when selecting a TCXO oscillator is the temperature coefficient requirement. The temperature coefficient of an oscillator is defined by its relative frequency change over temperature, and is usually expressed in “ppm/°C”. The ECX-H27CM-50.000 features an extremely low temperature coefficient of 10 ppm/°C, and is therefore ideal for applications where temperatures may vary significantly over time.

In conclusion, the ECX-H27CM-50.000 oscillator is a reliable and highly precise TCXO oscillator, and it is well suited for applications where temperature control and high accuracy requirements are of critical importance. The oscillator represents the industry standard for frequency and stability control over temperature, and is widely used in a wide variety of fields.
