Introduction

Oscillators are electrical devices that generate a sinusoidal output signal with a frequency that almost always has a consistent constant value. It can provide the desired electrical signals for the operation of various electronic circuits and is widely used in the fields of radio, communication, computers, digital audio, and other related industries. Here, we mainly talk about the 500DSAD100M000ACFR oscillator and its application field and working principle.

Overview of the 500DSAD100M000ACFR Oscillator

The 500DSAD100M000ACFR oscillator is a surface-mount quartz common-mode oscillator. It utilizes the vibration of quartz as a vibration source, which is produced by lapping the two sides of a quartz wafer to generate microscopic pyramidal depressions on both sides. The thickness of the quartz membrane oscillator is about 0.3 mm. Its chip uses a high HCMOS process and its output frequency stability is at about 10-6. The 500DSAD100M000ACFR oscillator has a wide frequency range of 10MHz~100MHz and it integrates the crystal oscillator and the match resistor. The package size is 2.5mm x 2.0mm and it is RoHS compliant. It has low power consumption and operates at 5V supply voltage.

The 500DSAD100M000ACFR is a versatile oscillator that can be used for different applications. It can be used as a frequency reference in communications systems, such as GSM, CDMA, WCDMA, EVDO, etc. It can also be used for frequency stabilization applications in network systems and computer systems. Additionally, the 500DSAD100M000ACFR oscillator is used as an oscillation source in digital audio systems, DVD players, set-top boxes, and radio receivers.

Working Principle of the 500DSAD100M000ACFR Oscillator

The 500DSAD100M000ACFR oscillator uses a quartz crystal as its vibration source, whose structure consists of two parallel vibrating quartz plates. When the quartz crystal is subjected to the alternating voltage of the drive signal source, it vibrates with an alternating movement along the thickness direction, which causes surface movement. The whole process is a resonance phenomenon. The resonance frequency of the quartz crystal is determined by its physical structure. The output frequency of the oscillator is determined by the resonance frequency of the quartz crystal and the driving voltage.The 400DSAD100M000ACFR oscillator has a built-in circuit for frequency control. The circuit consists of an amplifier, a filter, and a voltage regulator. When the drive voltage is constant, the resonance frequency of the quartz crystal can remain the same. With matched components, the frequency of the oscillator can remain stable over temperature, supply voltage, and other changes.

Conclusion

The 500DSAD100M000ACFR oscillator is a quartz common-mode oscillator that is widely used for different applications, such as communications systems, network systems, computer systems, digital audio systems, DVD players, set-top boxes, and radio receivers. It has low power consumption and its output frequency stability is at about 10-6. The working principle of the 500DSAD100M000ACFR oscillator relies on the vibration of quartz based on its physical structure, and then the built-in frequency control circuit for stability and consistency of its output frequency.
