Oscillators

Oscillators are components used to generate a periodic waveform. The 520T05HA38M4000 is an ultra-low noise, high stability crystal oscillator used in many oscillator applications. It boasts up to six different package sizes and a frequency range of 4-55 MHz.

Application Field

The 520T05HA38M4000 is frequently used in telecommunications equipment, such as routers, modems, and access points. It is also used in frequency synthesizers, receivers, and transceivers. The device is especially suited for spectrometers, especially those that measure mass spectrums.

Working Principle

The 520T05HA38M4000 utilizes a quartz crystal oscillator to generate a periodic waveform. Quartz crystals are naturally cut and polished to a specific frequency, which can then be amplified and tuned. The frequency can be further adjusted using external components such as varactors or capacitors. The device then amplifies and transmits the signal as a low-noise output.

The 520T05HA38M4000 also utilizes temperature compensation techniques to ensure accurate output frequencies across varying temperatures. This is achieved by using an on-chip integrated temperature sensor. This sensor measures the ambient temperature of the device which is then used to adjust the output frequency.

The 520T05HA38M4000 also utilizes a phase-locked loop (PLL) architecture. This architecture uses a feedback loop to synchronize the oscillator’s output frequency with a reference frequency. This ensures that the output frequency is always accurate and stable.

Conclusion

The 520T05HA38M4000 is an ultra-low noise, high stability crystal oscillator used in many oscillator applications. It boasts a frequency range of 4-55MHz and up to six different package sizes. The device is frequently used in telecommunications equipment, such as routers, modems, and access points, as well as in spectrometers and frequency synthesizers. It utilizes a quartz crystal oscillator, temperature compensation, and a PLL architecture to guarantee accurate and stable output frequencies across varying temperatures.
