Introduction to Oscillators An oscillator is an electrical circuit that produces a steady periodic signal, such as a sine wave, a square wave, or a saw-tooth wave. Oscillators are used in a variety of electronic circuits to produce a signal that goes back and forth between two points repeatedly. Oscillators are often used as timing devices to produce a signal for a timer circuit or to keep the oscillator in a frequency range.ASTMHTV-120.000MHZ-ZR-E Application Field and Working PrincipleThe ASTMHTV-120.000MHZ-ZR-E oscillator is an integrated oscillator module that provides an excellent thermal stability and a long-term operational stability. This oscillator is designed for use in a variety of applications such as frequency synthesizers, audio systems, medical equipment, instrumentation, and communications equipment.The primary function of an oscillator is to generate an electrical signal at a specific frequency. This signal can then be used in a variety of electronic circuits. The ASTMHTV-120.000MHZ-ZR-E oscillator operates by using an integrated resonator structure which creates a series of sine waves with a frequency of 120.000 MHZ (megahertz). This resonator structure is called a Quartz Crystal Resonator (QCR).The QCR is a Quartz Crystal which is cut in a certain shape, and the two flat faces of the crystal are ground and polished. The QCR has a piezoelectric effect which causes it to vibrate at a certain frequency when an alternating current is applied to the crystal. By controlling the frequency of the alternating current, the QCR can be used to generate a signal at a specific frequency.The QCR is connected to two amplifiers, one for the feedback signal and one for the output signal. The amplifier used for feedback signal is an inverting amplifier which has a very high impedance and can be used to provide precise frequency regulation. The amplifier for the output signal is a non-inverting amplifier which is used to increase the output signal level so that it can be used in other circuits.The output signal of the oscillator is then used to drive various other circuits. In high speed circuits such as frequency synthesizers, the output of the oscillator needs to be very stable and should not vary from the set frequency even when the temperature changes. The ASTMHTV-120.000MHZ-ZR-E oscillator utilizes temperature compensation techniques to minimize the effect of temperature variations on the frequency of the output signal.The ASTMHTV-120.000MHZ-ZR-E oscillator is a reliable and stable oscillator with a long life and a reliable output signal. It is designed to provide excellent performance in a variety of applications such as frequency synthesizers, audio systems, medical equipment, instrumentation, and communications equipment.
