Oscillators are known as the key components used in many applications which require precise time interval and frequency control. 578L288CTT is an inductance-capacitance (LC) crystal oscillator that features high frequency, excellent temperature stability and low phase noise, making 578L288CTT widely applicable to applications with stringent requirements. This article reveals the 578L288CTT application field and the working principle of it.

578L288CTT Application Field

578L288CTT crystal oscillator is suitable for any applications which have stringent requirement when it comes to time interval and frequency stability. Specifically, 578L288CTT is the preferred choice for military and aerospace systems, industrial devices, microwave applications, high frequency power generator, navigation systems, and devices which require high level of reliable signal source. In addition, 578L288CTT is recommended to use in PON, PCS/CDMA base station, TD-SCDMA base station, global positioning system, optical microphone system, navigation system, and superior-class motorboat system.

578L288CTT Working Principle

The working principle of 578L288CTT mainly relies on LC tuning. LC tuning is a kind of frequency controlling technique which utilizes the interactive effect of inductance and capacitance of an LC circuit. The inductance and capacitance of the 578L288CTT crystal oscillator are arrayed as resonant components to form a LC circuit. Thus, when a suitable voltage is applied to the oscillator, the LC circuit will vibrate at its resonant frequency (FR), resulting in a stable oscillation. Thanks to this operation principle, the 578L288CTT crystal oscillator is able to achieve a frequency less than 25MHz with high frequency stability and excellent environmental tolerance. Besides, 578L288CTT adopts special digital algorithm to improve its frequency accuracy even further. This is achieved by customizing the chip design with a data-controlled DDS, which controls the oscillator\'s clock speed, phase and frequency, in order to shorten the calibration time. While in operation, 578L288CTT changes the reference data of its frequency suppliers in real time in order to adapt to different environmental conditions, thus enhancing its stability accordingly. This also makes 578L288CTT suitable for mass production, greatly reducing its production cost.

Conclusion

Thanks to its exceptional performance characteristics and outstanding capability of environmental adaptation, 578L288CTT is widely used in numerous applications including military and aerospace systems, industrial devices, microwave applications, high frequency power generator, navigation systems, and PON/PCS/CDMA/TD-SCDMA base stations. Moreover, its working principle relies on LC circuit tuning and data-controlled DDS technology, allowing it to reach a frequency lower than 25MHz with excellent frequency stability and environmental tolerance. In conclusion, 578L288CTT is an ideal oscillator for applications with stringent performance requirements.
