Oscillators: 500SAAA16M3840ACFR Application Field and Working Principle

Oscillators are electronic components that develop electrical sine waves with accurate frequency. Oscillators are used in practically all electromagnetic devices, including clocks, radios, and computer hardware. They usually oscillate at a specific frequency or create a range of frequencies, depending on the requirements of the user. This article looks at the 500SAAA16M3840ACFR oscillator and its application field and working principle.

Application Field

The 500SAAA16M3840ACFR oscillator is an all-surface mount, low phase noise voltage-controlled crystal oscillator (VCXO). It is designed for use in various industries, including medical, military, aerospace, laboratory, and industrial applications. It offers dynamic frequency tuning capability from 500S125/250/375 HZ to 16M3840MHz and is capable of controlling crystal cuts of different shapes and sizes. It is packaged in an industry standard 8 pin ceramic package.

The 500SAAA16M3840ACFR oscillator offers excellent phase noise performance and stability. It features a wide tuning voltage range of 0V to 3.3V, low power consumption, and a fast settling time. It also provides a wide operating temperature range of -40°C to +85°C and extended shock and vibration performance.

Working Principle

The 500SAAA16M3840ACFR oscillator works on the principle of electronic feedback. Electrical signals oscillate between two energy states at a certain frequency, forming an electrical waveform. This frequency is determined by the component\'s resistor-capacitor (RC)circuit, also known as a "tank circuit." The oscillator generates an alternating electrical signal (oscillation) with a frequency determined by the RC circuit. The oscillator\'s frequency is controlled by a voltage-controllable crystal (VCXO).

The VCXO is a two-port active electronic device that is used to control the frequency of the oscillator. It consists of a quartz crystal resonator and a semiconductor to serve as a frequency-determining element. The quartz crystal is placed in a resonant circuit and is made of two cross-sections of quartz of specific thickness, with electrodes on the four corners. This resonator is coupled to the semiconductor, which amplifies the output signal.

When the oscillator is activated, the VCXO controls the frequency of the oscillation between the two energy states. The frequency of the oscillation is determined by the quartz crystal. When the voltage supplied to the VCXO is increased, the frequency of the oscillation also increases. Conversely, when the voltage is decreased, the oscillation frequency decreases. This allows for precise frequency control.

Conclusion

The 500SAAA16M3840ACFR oscillator is a low phase noise voltage-controlled crystal oscillator designed for use in various industries. It offers dynamic frequency tuning capability, excellent phase noise performance, and a wide operating temperature range. It operates on the principle of electronic feedback and uses a voltage-controllable crystal to control the frequency of oscillation. This oscillator is an ideal solution for applications requiring precise frequency control and reliable performance.
