Oscillators have the basic property of generating a periodic electrical signal, and the XLH735100.000000I oscillator is no exception. In this article, we discuss the application field and working principle of the XLH735100.000000I oscillator, in order to better understand its features and operation.

Application Field

The XLH735100.000000I oscillator is primarily employed for applications requiring precise and stable frequency output, such as clock management in ordinary consumer electronics equipment, such as the TV, air conditioner, microwave oven, etc. This type of oscillator can provide the performance of a quartz oscillator with less cost, especially for applications in which the frequency to be generated is low. The frequency stability is usually within 0.2 ppm, and sometimes there is no requirement on temperature characteristics, which makes it easy to use.

The XLH735100.000000I oscillator also can be used for general frequency control without temperature compensation. Furthermore, it can achieve both frequency control and temperature compensation with a single integrated chip, which makes it suitable for satellite communication modules and television broadcasting equipments.

Working Principle

The XLH735100.000000I oscillator consists mainly of an ECL gate array, a frequency-dividing circuit, and a quartz crystal. The frequency of the oscillator is determined by the quartz crystal, which is driven by an externally supplied voltage (VCC). In the frequency-dividing circuit, a frequency-multiplying or -dividing ratio is set by selecting an appropriate set of logic gates, and the filtered output of the divided frequency is sent to the ECL gate array for shaping.

The ECL gate array consists of two voltage controlled gain stages and an output buffer. The output waveform is determined by the gain values of the two stages, and the feedback from the output stage ensures the loop gain of the oscillator is always greater than unity. The gain instability of the gain stages is compensated by the frequency dividing circuit, which ensures the output waveform is always stable.

Conclusion

To summarize, the XLH735100.000000I oscillator is an optimal solution for applications requiring precise and stable frequency output. It is mainly used for clock management in consumer electronics equipment, and is also suitable for general frequency control and satellite communication modules. The frequency element of this oscillator is a quartz crystal, the frequency stability is usually within 0.2 ppm, and the output waveform is determined by the ECL gate array.
