The oscillator also has a wide variety of applications in communication networks, clocks, video systems, and other industrial equipment.

Working Principle

The 531EA156M000DG oscillator uses a temperature-compensating quartz crystal as its frequency reference. The quartz crystal is tuned to a specific frequency and then an adjustable amplifier is used to boost its voltage to the desired level. A phase-locked loop (PLL) circuit is used to lock the amplifier\'s output to the quartz crystal oscillator frequency. This ensures that the oscillator output frequency is kept at its predetermined value, regardless of external factors such as temperature and age.

The PLL circuit consists of several components, such as a phase detector, a filter, and a voltage-controlled oscillator (VCO). The phase detector is used to compare the frequencies of the quartz crystal oscillator and the VCO output. The phase detector then generates a control signal that is used to adjust the frequency of the VCO output, such that it remains in sync with the quartz crystal frequency. The filter is used to reduce noise in the control signal, while the VCO amplifies the signal to generate a frequency-stabilized output.

The 531EA156M000DG oscillator is designed with a wide temperature range, low phase noise, and a very stable frequency accuracy. Its excellent signal isolation ensures that the signal is not affected by external factors and its low power consumption makes it energy efficient. Its robust design and high reliability make the 531EA156M000DG an ideal choice for a variety of applications.
