Oscillators are electronic equipment used to generate periodic electrical signals. They can generate square wave, sine wave, sawtooth wave, triangular wave or even other waveforms. A 520R10DA16M3690 oscillator is a type of oven-controlled oscillator circuit that can generate an accurate and stable signal for a wide variety of frequency and low noise applications. In this article, we will discuss the application fields and working principles of a 520R10DA16M3690 oscillator.

Application of 520R10DA16M3690 oscillator

A 520R10DA16M3690 oscillator is mainly used in communication and navigation systems, systems or devices that require accurate frequency. The applications of this oscillator include but are not limited to: cellular basestations, navigation systems, precision radar antenna positioning, frequency synthesizers, wireless LAN’s, satellite communications, GPS applications and military communications. The working frequency range of the 520R10DA16M3690 oscillator can reach over 10GHz. It is also suitable for high-accuracy phase-locked loops that require long-term frequency stability across a wide temperature range. The stability of the generated signals can be as high as 10-13 for long periods.

Working principle of 520R10DA16M3690 oscillator

The 520R10DA16M3690 oscillator is a TCXO (Temperature Compensated Crystal Oscillator). This type of oscillator is not only temperature compensated, but also power supply supported. It has an internal oven that encapsulates the crystal and maintains a constant temperature by using a heater. This helps to reduce the sensitivity of the quality factor of the crystal against temperature variations. The oven also eliminates the need for external control circuitry.

The operation of the 520R10DA16M3690 oscillator starts with an external AC power supply applied to the external connections of the oscillator. The AC power is converted to a DC voltage which is then used to heat the thermistor in the oven. The thermistor serves as a temperature sensor that monitors the temperature of the oven. The voltage output of the thermistor is then fed back to the control amplifier, which in turn adjusts the heater to maintain a constant temperature in the oven. The temperature of the crystal is then kept constant, thus ensuring a highly accurate and stable output frequency.

The 520R10DA16M3690 oscillator has a wide range of frequency range and stability. It is ideal for applications requiring accurate frequency and low noise. The accurate frequency and stability of the signal make it an ideal choice for frequency synthesizers, navigation systems and other high-precision systems.
