Programmable Oscillator is one of the most versatile and widely used tool for engineers who design electronic systems. SIT9005ACU1H-28DF is a type of programmable oscillator, specially designed for use in embedded systems, automotive electronics, industrial automation and consumer electronic applications. This article will discuss the application field and working principle of the SIT9005ACU1H-28DF.

The most important parameters for embedded systems applications are low power consumption, low cost, high performance and high reliability. The SIT9005ACU1H-28DF is designed to be cost-effective and provide high performance. It has a built-in ultra-low power supply voltage regulator which allows it to run on just 8V, while also providing high precision, low jitter clock oscillations. Furthermore, its built-in power fail detector allows it to automatically switch from high precision to low power consumption modes when power is interrupted, so that the device can still provide reliable clock signals.

The SIT9005ACU1H-28DF is also designed for automotive and consumer electronic applications. Because of its low jitter and high repetitive accuracy, it can generate highly reliable clock signals for data communications, so it can be used in vehicles/automobiles to provide a stable and reliable clock signal. Furthermore, its fast start-up time and low power consumption makes it suitable for consumer electronics such as set-top boxes and digital TVs.

As mentioned above, the SIT9005ACU1H-28DF is a programmable oscillator. Its working principle is based on the piezo-electric effect. In the piezo-electric effect, when a piezoelectric crystal is subjected to a voltage, it deforms and generates a mechanical force. This force can be used to deform another crystal in a feedback loop. The frequency of the oscillations is determined by the characteristics of the piezoelectric crystal and the feedback loop.

The SIT9005ACU1H-28DF uses a programmable quartz crystal. The frequency range is from 200kHz to 160MHz and the minimum frequency step size is 0.1Hz. It can be programmed via the serial port and it supports SPI, I2C, UART and LIN bus protocols. The device also has built-in temperature compensation and automatic gain control. This ensures that the clock signals have consistent frequency and stability, even in wide temperature range.

In conclusion, SIT9005ACU1H-28DF is a type of Programmable Oscillator designed for use in embedded systems, automotive electronics, industrial automation and consumer electronic applications. Its working principle is based on the piezo-electric effect and it can be programmed via the serial port. It has low jitter and high repetitive accuracy, making it ideal for use in data communication devices. Finally, its built-in power fail detector and temperature compensation make it suitable for robust operation in wide temperature range.
