 Oscillators are electronic circuits that generate periodic waveforms. In particular, ASET-12.288MHZ-Y-T oscillators are widely used in systems that require precise, low jitter frequency sources. An output drive of up to 3.5V from an input of 0.5V is often required in these systems.

Application Field

ASET-12.288MHZ-Y-T oscillators are used in a wide range of applications including telecommunication, automotive, medical, industrial, and consumer electronics. They are also used for timing, clock and frequency synthesis, as well as other signal processing tasks. In addition, they can be deployed in CPU motherboard clock generators, digital audio systems, network base station radios, HDTVs, and more.

Working Principle

The ASET-12.288MHZ-Y-T oscillator utilizes a quartz piezo-electric resonator, the internal resonator frequency, and integrated capacitors and resistors to control the oscillation frequency when it is applied to a voltage source. The resonator is typically composed of two parts, one of which consists of a quartz crystal or piezo-electric material and the other is a capacitor with adjustable load capacitance.

The quartz crystal is responsible for the oscillator\'s high frequency accuracy and stability, and determines the fundamental frequency of the oscillator. The load capacitance acts as a load factor, or tuning element, which adjusts the natural frequency of the quartz crystal. When the quartz is loaded, its frequency value is determined by multiplying the fundamental frequency with a main factor of 2 and then adding the load factor.

The changing of the load capacitance will cause the oscillator to produce its output at a different frequency. This is a relatively volatile procedure because any minute changes in the load capacitance will cause the output frequency to shift. Therefore, the load capacitance must be maintained in a relatively stable state in order to ensure that the output frequency remains within the expected range.

In order to increase the frequency of the oscillator, the integrated capacitors and resistors can be adjusted. The capacitors form a parallel tuned circuit with the quartz crystal, which, when driven, serves to increase the oscillator frequency. The resistors from a voltage divider with the capacitors and thus further increase the frequency. In combination, the capacitor and resistor network permits very precise frequency control, allowing the oscillator to produce an exact frequency.

The output power of the ASET-12.288MHZ-Y-T oscillator is limited by the output capability of the circuitry, but the low jitter oscillator produces a very stable signal. The low phase jitter and extremely accurate clock rate provide excellent performance and reliability for the oscillator.

Conclusion

The ASET-12.288MHZ-Y-T oscillator is a versatile and highly accurate device used in a wide range of applications in telecommunication, automotive, medical, industrial, and consumer electronics. Its frequency control is enabled by the quartz crystal and RC components, while its output power is limited by the circuitry. As its low jitter oscillator produces an extremely stable signal, it provides excellent performance and reliability, making it a reliable choice for all sorts of projects.
