Oscillators - OYETGHJANF-66.667000 Application Field and Working Principle

Oscillators are electronic circuits that produce regular, alternating signals of a known frequency. The OYETGHJANF-66.667000 is a type of oscillator used particularly in ultra-high frequency (UHF) and microwave range applications. It features a frequency stability of ±2.0 ppm/°C, and a small form factor of 5.9mm x 12.7mm.

Application

OYETGHJANF-66.667000 oscillators are used in a variety of applications. The small form factor, frequency stability, and wide operating temperature range make them ideal for applications that require miniature size and low-power operation. These oscillators are used in cellular phones, Global Positioning Systems (GPS), radio control systems, digital satellite receivers, and portable audio players.

Working Principle

The OYETGHJANF-66.667000 oscillator works on the principle of electronics components integrated together to build a stable signal generator. In this type of oscillator, two resistors create a voltage divider, while a capacitor provides timing control. This is referred to as an RC oscillator circuit. In addition to the resistors and capacitor, a transistor is used as an amplifier and switch to generated the oscillations.

The transistor can be switched on and off to alter the voltage across the capacitor. When the transistor is switched off, current flows from the resistor to the capacitor, increasing the voltage and charging the capacitor. When this voltage reaches a certain level, a threshold voltage, the transistor switches on. The transistor then shorts out the capacitor, discharging it quickly. This creates a pulse signal, which is then amplified and sent to the output.

This type of oscillator is used because it provides a low cost but extremely high-quality signal generator. It is able to generate stable and precise signals in the UHF and microwave frequency ranges. The frequency of the signal can be adjusted easily by changing the values of the resistor and capacitor.

Conclusion

The OYETGHJANF-66.667000 oscillator is a type of high-precision, high-frequency oscillator used in a variety of applications, from cellular phones to digital satellite receivers. It features a small form factor, high frequency stability, and wide operating temperature range. The working principle of the oscillator relies on the integration of two resistors, a capacitor, and a transistor to generate a stable frequency signal.
