SIT9005ACT2D-30DD

Programmable Oscillators play an essential role in many electronic systems and are widely used in both analog and digital circuits. In this article, we will discuss the application field and working principle of the SIT9005ACT2D-30DD Programmable Oscillator.

The SIT9005ACT2D-30DD Programmable Oscillator is a high-precision, low-power device designed for timing control applications. It is specifically designed for use in temperature-critical positioning systems where power efficiency, low jitter, and precision timing are essential. It can be used as a clock and timer in digital circuits, as a voltage-controlled oscillator (VCO) in analog circuits, or as a programmable oscillator in digital signal processing (DSP) systems.

The main feature of this Programmable Oscillator is its excellent power efficiency. It has a low supply voltage range of 1.1V to 3.3V, making it ideal for low-power applications. It also has an impressive 10µA standby current and a programmable switching frequency between 0.1MHz and 30MHz. Furthermore, the device features an auto-dual power source (VDD) and can switch between the two frequencies seamlessly. This helps to provide maximum power efficiency for systems that require frequent low-power transitions.

In regards to accuracy and stability, the SIT9005ACT2D-30DD Programmable Oscillator offers outstanding performance. Its frequency stability is rated at ±50 ppm over the commercial range, which covers a temperature range of between -40ºC and +85ºC. Its accuracy is rated at 0.3% over the entire operating temperature range, and its jitter performance is rated at better than 0.4ps. This makes it an ideal choice for applications that require precise timing control.

The working principle of SIT9005ACT2D-30DD Programmable Oscillator can be divided into two parts. First, it uses an integrated voltage-controlled oscillator (VCO) to generate an accurate frequency output. The VCO consists of a quartz crystal and an integrated circuit (IC) with necessary logic elements and analog components. The quartz crystal acts as a reference frequency that is tuned to a specific value while the IC adjusts the frequency generated by the quartz crystal. The crystal and IC work in tandem to generate the desired frequency output.

In the second part of the working principle, a timer circuit is used to further modify the frequency output from the VCO. This timer circuit can be programmed to change the frequency output in either an up or down direction, depending on the application. This allows for adjustable and precise timing control. The timer circuit can also be used to enable and disable the oscillator for power savings.

Overall, the SIT9005ACT2D-30DD Programmable Oscillator offers outstanding accuracy, stability and power efficiency. It is ideal for timing control applications, such as digital circuits, analog circuits, and DSP systems, where precision timing and low-power operation are required. With its impressive power efficiency and excellent frequency stability, it makes an excellent choice for demanding and temperature-critical applications.
