Oscillators encompass a wide range of devices that are designed to produce an output signal of pre-defined frequency. One such oscillator is the ASA2-64.516MHZ-L-T oscillator, which is a low noise, low jitter device designed to meet tight frequency accuracy requirements. This article describes the application fields of the device and its underlying working principle.

Application Fields

The ASA2-64.516MHZ-L-T oscillator is a versatile device that is used in a variety of applications. It is suitable for use in wireless Bluetooth technology, as it has a low phase noise which is crucial for reliable and effective data transfer. The device is also used in television broadcasting, where it is used to generate the local oscillator required for frequency conversion. It is also used to clock logic devices or microprocessors, where high performance is essential for error free operation. In addition, this device is also suitable for use in a range of test and measurement equipment, including signal generators, spectrum analyzers and vector network analyzers.

Working Principle

The ASA2-64.516MHZ-L-T oscillator is a fundamental-mode device based on the AT-cut quartz crystal specially designed for applications with tight frequency accuracy requirements. The oscillator is an LC-tank implemented with a CMOS IC and a quartz crystal resonator. Quartz crystals have an inverse relationship between frequency and temperature, meaning that a higher frequency is required as the temperature drops. The device is designed to compensate for this frequency variation, resulting in a highly stable output signal. Furthermore, the oscillator provides a low phase noise, which is essential for reliable communications and data integrity.

The oscillator consists of two components: a CMOS IC and a quartz crystal resonator. The IC works as a loop controller, which is responsible for controlling the signal amplitude and frequency. The quartz crystal resonator works as a frequency reference, which provides a precise output frequency and a low phase noise. The loop controller and the quartz crystal resonator are connected in a feedback loop via an amplifier. This helps to ensure a stable and precise output frequency over a wide range of temperatures.
