Introduction

Programmable oscillators, such as the SIT9005ACT2D-18EJ, are versatile electronic components capable of delivering stable timing signals with frequency and amplitude control. In this article, we will discuss the application field and working principle of the SIT9005ACT2D-18EJ.

Application Field

The SIT9005ACT2D-18EJ programmable oscillators are widely used in a range of applications including industrial, automotive, consumer electronics and network communications. Its primary use is for high-precision timing and synchronization for digital equipment, providing an efficient and reliable basis for information transmission and data processing. The SIT9005ACT2D-18EJ is also used in audio recording and playback devices, including microphones and powered speakers, due to its impressive timing accuracy and stable performance. Industrial control systems, from factory automation to robotics, also employ these programmable oscillators due to their repeatable performance. The SIT9005ACT2D-18EJ is finally used in telemetry systems, in order to ensure exact timing of data collection and transmission.

Working Principle

The SIT9005ACT2D-18EJ contains an electrical circuit, consisting of a quartz crystal and the associated oscillator circuitry, which generates a periodic signal at a fixed frequency with a very low degree of oscillator drift. When an alternating voltage is applied to the quartz crystal, an electric field is generated and deforms the crystal lattice. This deformation causes the quartz crystal to vibrate at a frequency determined by its physical structure and results in a periodic signal. This signal is then filtered and amplified by the oscillator circuitry to generate a stable output signal at the desired frequency.The SIT9005ACT2D-18EJ features a thermally stabilized design, which effectively compensates for any variation in temperature and humidity, ensuring a stable and consistent output signal. It is also easy to program and configure, allowing the user to change the output frequency via a simple programming interface.

Conclusion

The SIT9005ACT2D-18EJ is a highly reliable and adjustable programmable oscillator, capable of delivering stable and accurate timing signals with a wide range of applications, from audio recording and playback to industrial automation. Its onboard thermally stabilized design ensures consistent performance, even when subject to extreme environmental conditions.
