Crystals are the backbone of modern technologies, ranging from handheld phones to large scale communications systems. The FA2016AS 19.2000MF12Y-AG0 is one form of crystal that has been developed specifically to provide precise oscillations and precise timing accuracy in broadcasting and navigational systems. This article examines the application field and working principle of this crystal oscillator.

Application Field

The FA2016AS 19.2000MF12Y-AG0 crystal is designed for high-end digital broadcasts, satellite-based navigation systems, telecommunications systems, and time-keeping systems. It is especially suitable for complex industrial applications which require precise frequency control. This crystal oscillator has been designed to provide very low jitter (typically in the range of 0.1 - 0.4 psec) and low phase noise of -125 dBc/Hz at 10KHz frequency offset. These features make this crystal oscillator an ideal choice among engineers.

Working Principle

The FA2016AS 19.2000MF12Y-AG0 crystal is based on quartz electrostriction, a phenomenon in which quartz\'s physical dimensions change when an electric field is applied. The physical changes are converted to electrical signals which are then used to generate an oscillation. The oscillation frequency is determined by the physical properties of quartz, including its stiffness, shape, and the size of the electrodes on the quartz. The oscillations of the crystal can be tuned to a precise frequency to provide a high-precision timing reference for navigation and broadcast systems.

The oscillator is controlled by a temperature-compensated voltage-controlled oscillator (TCVCXO). This is a self-tuning system which uses the oscillator\'s voltage to adjust the frequency. The output frequency is corrected by an internal compensation mechanism to ensure accurate frequency control in varying environmental conditions, including low and high temperatures. This allows the oscillator to maintain a precision oscillation with minimal power consumption.

Conclusion

The FA2016AS 19.2000MF12Y-AG0 crystal oscillator is designed for precision timing and frequency control applications, especially in broadcasting and navigation systems. Its low jitter, low phase noise, and temperature compensation features make it an ideal choice for complex industrial systems. By employing quartz electrostriction and a temperature controlled voltage controlled oscillator, the crystal oscillator can provide accurate frequency control with minimal power consumption. This makes it an outstanding choice for a variety of applications.
