Oscillators

An oscillator is an electronic device circuit designed to produce a continuous output signal at or near a certain frequency. ASTMHTE-12.000MHZ-ZJ-E is an oscillator that can provide frequency stable sinusoidal wave outputs with high accuracy, small size, low power consumption, and high temperature stability.

Application Field

ASTMHTE-12.000MHZ-ZJ-E is widely used in many different industries, such as avionics, radio, communication, automotive, industrial, medical, test equipment, military, and research and development. It can be used to generate clocking signals for digital circuits, provide reference signals for RF communications, time synchronization on network systems, frequency synthesis, and many other purposes.

Working Principle

ASTMHTE-12.000MHZ-ZJ-E utilizes a PLL (phase locked loop) circuit as the main oscillating circuit. PLL uses a feedback loop and comparator to achieve a stable oscillator frequency that is isolated from the temperature and voltage changes inside the circuit. The feedback loop takes an input voltage and compares it to a reference voltage. If there is any difference between the two voltages, the PLL adjusts the output voltage to bring the two close to one another.

The PLL is composed of three main blocks, an oscillator circuit, a phase detector, and a frequency divider. The oscillator circuit generates a sine wave signal of a certain frequency. The phase detector compares the signal to the reference signal and produces an error signal if there is any mismatch. The frequency divider then divides this error signal into a lower frequency signal, which is then fed back into the PLL’s oscillator.

The operation of ASTMHTE-12.000MHZ-ZJ-E PLL is based on a negative feedback control. As the oscillator generates a signal, the difference between the oscillator signal and the reference signal is detected by the phase detector. This difference is then used to control the frequency divider to adjust the oscillator’s output frequency. As the feedback loop adjusts the frequency according to the reference signal, the oscillator will remain at a constant frequency as long as the reference signal is stable.

Conclusion

ASTMHTE-12.000MHZ-ZJ-E is a highly accurate and reliable oscillator that can provide a stable sinusoidal output at a preset frequency. It is widely used in many industries due to its small size, low power consumption, and high temperature stability. The device is composed of a PLL circuit, which utilizes a feedback loop to achieve a stable output frequency. The device is also able to accurately regulate its output frequency based on the input of a reference signal, making it a good choice for applications that need a stable output signal.
