Oscillators, also known as timing sources, are used to generate periodic, regular electrical signals, usually in the form of a sine wave, to facilitate functions such as frequency division, frequency measurement, and time control. The ASTMUPCFL-33-12.000MHZ-EJ-E-T3 oscillator is a type of Voltage Controlled Oscillator (VCO) that is commonly used in portable electronic devices due to its small size and low power consumption. This article will explore the application field and working principle of this device.

Application Field

The ASTMUPCFL-33-12.000MHZ-EJ-E-T3 oscillator is a compact and lightweight device that can be used in a wide variety of applications, including clock generation for microprocessors, video processors, communication systems, and sensors. Due to its low power consumption, the device does not require the use of a large power supply, making it suitable for portable devices. Additionally, the device is designed to be extremely reliable and accurate, with a frequency stability of up to 0.15 parts per million over an operating temperature of up to -40°C to +85°C.

Working Principle

The ASTMUPCFL-33-12.000MHZ-EJ-E-T3 oscillator works by using an integrated circuit (IC) to generate a square wave signal. The IC contains a voltage control element which is capable of adjusting the voltage applied to the CMOS (complementary metal-oxide-semiconductor) circuit. The oscillator then uses this signal to generate a sinusoidal wave with a frequency of 12 Mhz. The device also contains two clock inputs - a bypass clock input, and a programmable clock input - which can be used to control the frequency of the output signal. The programmable clock input can be used to adjust the frequency from 0.2 to 15 MHz.

The device also contains a Reference Phase Frequency Detector (RPFD) which can be used to detect and correct minor frequency variations in the output signal, allowing for more precise frequency control. The device also contains an integrated temperature sensor, which can be used to measure the temperature of the circuit and adjust the voltage control element to maintain a stable frequency.

Conclusion

The ASTMUPCFL-33-12.000MHZ-EJ-E-T3 oscillator is a small, lightweight, and power-efficient device that is commonly used in portable electronic devices due to its low power consumption. The device is capable of generating a sinusoidal wave with a frequency of up to 15 MHz and has a frequency stability of up to 0.15 parts per million over an operating temperature of up to -40°C to +85°C. It also contains two clock inputs which can be used to control the frequency of the output signal, a Reference Phase Frequency Detector (RPFD) which can be used to detect and correct minor frequency variations in the signal, and an integrated temperature sensor which can be used to adjust the voltage control element.
