Programmable oscillators are often essential components in electronic products, responsible for generating electrical signals that are used to control the frequency, phase and amplitude of other oscillators and function as communications with other systems. One type of programmable oscillator is the SIT9005ACR1G-25NN. This article will discuss the application field and working principle of the SIT9005ACR1G-25NN.

The SIT9005ACR1G-25NN is a miniature, surface-mount programmable oscillator, designed for use in avionics, automotive, and other industrial applications. It is capable of generating signals ranging from 25kHz to 156MHz and has a temperature range from -40°C to +125°C. The oscillator itself is a 1.1 x 0.9mm, fourth order Crystek quartz with a Sin/Cos output, which makes it ideal for applications in which high accuracy, reliability, and durability are required.

Given its versatile signal range, small size, and high temperature operating range, the SIT9005ACR1G-25NN has the ability to replace several components, greatly simplifying end user circuit design. It is also feature-packed, with an onboard voltage control, selectable output levels, and an internal EPROM memory that can store up to 64 different configuration options.

The SIT9005ACR1G-25NN works on a simple principle – the quartz crystal resonator is oscillated by an internal amplifier and voltage controlled current source, giving rise to an output signal. The oscillator is then programmed by an external programming voltage that determines the frequency, phase and output levels at which the signal will run. The oscillator has two basic modes – continuous and frequency hop – and can be configured to switch between them depending on the application.

The SIT9005ACR1G-25NN is particularly well suited to applications such as frequency modulation, frequency synthesis, precision timing, phase locking, pulse width modulation, and waveform generation. It is an excellent choice for automotive and avionics systems, where reliability and accuracy are essential. Not only is it reliable and accurate, but it is also capable of operating at a wide range of temperatures, making it suitable for use in a variety of environments.

In summary, the SIT9005ACR1G-25NN is a reliable, accurate, and feature-packed miniature programmable oscillator. Its versatile signal range and wide temperature operating range make it well suited for automotive and avionics applications, where it can replace several components, greatly simplifying end user design. It works on a simple principle, oscillating a quartz crystal resonator and being programmed with an external programming voltage.
