Oscillators: XLH730004.096000I Application Field and Working Principle

Oscillators are electronic components that work reliably in a wide range of operating frequencies or signal rates, and have wide application areas such as communication systems, aerospace, automotive, consumer and industrial electronics. The XLH730004.096000I oscillator is a high stability Oven Compensated Crystal Oscillator (OCXO) designed specifically for precision applications requiring low harmonic distortion, low phase noise, and low aging. This oscillator can be used in many applications with various operating frequencies between 4MHz and 78MHz.

The XLH730004.096000I oscillator combines a high premium quartz crystal, a precision electronic circuit, and a 9-4 cold-welded oven, which provides superior characteristics and frequency stability over a broad range of environmental conditions. The cutoff temperature of the oven can be finely adjusted to optimise performance. Alternatively, DC voltage or resistance can be applied to the oven to obtain temperature stability required for different applications.

The working principle of the XLH730004.096000I oscillator can be summarized as follows:

The quartz crystal used in the oscillator has two electrodes, one of which is the drive electrode and the other is the reactive electrode. When a control signal with a given drive frequency is applied to the drive electrode, the crystal vibrates in an elastic manner and resonates with the driving signal, producing an output signal with a given characteristic frequency. The resonator\'s resonance is dependent on the frequency and amplitude of the applied control signal, temperature, and load capacitance. This controls the frequency determined by the crystal itself. By adjusting the frequency of the control signal, it is possible to adjust the output frequency in a range that is limited by the characteristics of the crystal.

The ovenizing effect of the 9-4 cold-welded oven is used to keep the temperature stable during operation, resulting in superior performance characteristics and frequency stability. The high-precision electronic circuit drive circuit has a wide frequency control range and maintains the pulling performance of the oscillator to a low level. It also configures a reference temperature circuit in order to compensate for the change in frequency due to external temperature variation.

The XLH730004.096000I oscillator has a wide frequency range and low aging rate, making it suitable for many precision applications such as time and frequency standards, radar/tracking systems, airborne electronics and satellite systems. It can also be used in Wi-Fi, GPS, and cellular communications systems. The high stability and low harmonic distortion of the XLH730004.096000I oscillator make it an ideal choice for equipment requiring precise operation in demanding conditions.
