Programmable oscillators are electronic devices specifically designed to replace standard quartz crystal oscillators in order to provide more precise control over their frequency output. The SIT3822AC-1D-25NG is a programmable oscillator that is widely used for a variety of applications. This article will provide an overview of the application field of the SIT3822AC-1D-25NG as well as an explanation of its working principle.

Application Field of the SIT3822AC-1D-25NG Programmable Oscillator

The SIT3822AC-1D-25NG is a high performance, low power programmable oscillator that is widely used in the aerospace, military, and industrial sectors. Its key features include a low jitter of 0.6ps RMS and a wide operating temperature range of –40 to +85°C. The SIT3822AC-1D-25NG is also designed to be shock and vibration tolerant, making it well-suited for applications in harsh environments. The SIT3822AC-1D-25NG is typically used in applications such as frequency synthesizers, frequency stability regulators, clock recovery circuits, high accuracy time base controllers, and RF transceivers. This device is also capable of providing stable reference clock signals in a range from 12 MHz to 250 MHz.

Working Principle of the SIT3822AC-1D-25NG Programmable Oscillator

The working principle of the SIT3822AC-1D-25NG programmable oscillator is based on the use of a voltage controlled oscillator (VCO) to generate a reference clock signal. This VCO is divided into two parts: the internal VCO chain and the external VCO chain. The internal VCO chain consists of a feedback resistor and a varactor, which are connected in a closed loop. The external VCO chain is connected to the internal VCO chain and consists of an amplifier and a crank-like circuit. When an input control voltage is applied to the device, the internal VCO chain will adjust its frequency and the external VCO chain will adjust its amplitude, thus allowing the device to produce a precise and stable reference clock signal without any external frequency compensation.

The SIT3822AC-1D-25NG also features a programmable output voltage divider. This utilizes an external resistor and capacitor in order to divide the output frequency by a programmable factor, thus offering a wide range of frequency control capabilities. This feature allows for true frequency agility, making the SIT3822AC-1D-25NG ideal for applications that require high frequency resolution or control.

In addition, the SIT3822AC-1D-25NG features an integrated temperature compensation circuit. This circuit is designed to compensate for temperature variations that occur during the operation of the oscillator. By using this temperature compensation circuit, the device is able to maintain an extremely accurate frequency output over a wide temperature range.

The SIT3822AC-1D-25NG also features an integrated jitter attenuator. This reduces the RMS jitter from 0.6 ps down to 10 ps or less, thus improving the performance of the oscillator. This feature is especially beneficial for applications where precision is of the utmost importance.

The SIT3822AC-1D-25NG is a versatile and reliable programmable oscillator that can be used for a variety of applications. Its low power consumption and wide operating temperature range make it ideal for use in harsh environments. Additionally, its advanced features, such as the jitter attenuator and programmable output voltage divider, provide greater flexibility and performance. Thanks to these features, the SIT3822AC-1D-25NG is an ideal choice for applications that require high accuracy, frequency resolution, and stability.
