Oscillators

Oscillators are electronic components that create a steady and repetitive electrical signal. The primary function of an oscillator is to produce an output signal with a stable frequency. Oscillators are widely used in a variety of applications, anywhere from RF communication systems to systems that involve precise time measurement. The FDA620005 oscillator is a type of oscillator with some unique features.

FDA620005 Application Field

The FDA620005 oscillator is primarily used in temperature-sensitive applications, such as industrial data acquisition, automotive, home automation, industrial process control, medical devices, and consumer products. As its name suggests, the FDA620005 is an oven-controlled crystal oscillator (OCXO), meaning it is stable and efficient and can accurately maintain its frequency over a wide temperature range. Specifically, the frequency stability of the FDA620005 is 0.5ppm over a temperature range of -10 to 60 degrees Celsius.

FDA620005 Working Principle

The FDA620005 oscillator uses Environics\' patented Kyocera-patented electrothermal actuator, a single-crystal resonator, and a high-performance servo loop to maintain its frequency over temperature. First, the electrothermal actuator is used to precisely control the temperature of the resonator to within +/- 0.1 degrees Celsius. Next, the single-crystal resonator is frequency-controlled to generate an oscillation of a certain frequency. Finally, the high-performance servo loop is used to maintain the desired frequency accuracy of the oscillator in the presence of temperature, aging, and shock/vibration effects.

The advantages of FDA620005 oscillator are its low phase noise, fast warm-up time, wide operating temperature range, and low power consumption. In addition to its stability, the FDA620005 also offers frequency flexibility, meaning it can be programmed to run at any frequency from 16.7 to 100 MHz.

Conclusion

The FDA620005 oscillator is an oven-controlled crystal oscillator designed for temperature-sensitive applications. It utilizes Environics\' patented Kyocera-patented electrothermal actuator, a single-crystal resonator, and a high-performance servo loop to maintain its frequency over temperature. Additionally, the FDA620005 offers excellent phase noise performance, fast warm-up time, wide operating temperature range, low power consumption, and frequency flexibility. This makes it an ideal choice for applications that require precise frequency control over temperature.
