Oscillators

An oscillator is an electronic circuit that produces a repeating waveform, typically with specific frequency and amplitude. This waveform is used to create electrical signals or as a source of energy for various applications. In terms of its application field, oscillators are divided into three categories, namely quiescent, linear, and frequency hopping. ASD1-32.000MHZ-LR-T is a type of linear oscillator.

The ASD1-32.000MHZ-LR-T is an oscillator specifically designed to generate a linear signal of medium to low frequency. It has low noise, high stability, and low power consumption and is suitable for a variety of applications, such as automotive, aerospace, and industrial control. It is commonly used in video receivers, local oscillators, phase-locked loops, circuit controllers, and frequency hopping applications.

This oscillator consists of a quartz crystal, together with two transistors as active devices to provide the necessary gain. The crystal is connected in parallel to the collector of the first transistor and tuned to the desired output frequency by adjusting the load capacitor. This frequency can be as low as a few kHz up to 32MHz with a stability of 0.1 to 0.2ppm/°C. The second transistor amplifies and stabilizes the oscillation to create the necessary output signal. The output signal is typically adjustable +/-12.5% by the means of a varicap or 27 resistor.

The working principle of the ASD1-32.000MHZ-LR-T is similar to other types of oscillators. The quartz crystal is loaded in parallel to the transistor’s collector, and the frequency of the oscillation is determined by the burden condenser. When the transistor is biased into conduction, it creates positive feedback in the circuit, and the oscillations will begin. The frequency of the oscillations is determined by the charge and discharge time of the crystal.

The ASD1-32.000MHZ-LR-T is suitable for a variety of applications that require a low frequency and adjustable output. It can be used in video receivers, phase-locked loops, local oscillators, circuit controllers, and even frequency hopping applications. Its low noise and high stability make it ideal for long-term use, while its low power consumption makes it suitable for battery-operated devices.

In conclusion, the ASD1-32.000MHZ-LR-T is a linear oscillator suitable for medium to low-frequency applications. It has low noise and high stability, as well as adjustable output. This oscillator is commonly used in video receivers, local oscillators, phase-locked loops, circuit controllers, and frequency hopping applications.
