Programmable Oscillators

Programmable oscillators are a type of electronic oscillator that offers greater flexibility and higher performance than standard oscillators. They are used in a variety of applications, such as computer systems, medical equipment, industrial control systems, communications, power supplies, and aerospace systems.

SIT9002AI-28H25DD Application Field and Working Principle

The SIT9002AI-28H25DD is a dual-board programmable oscillator from NEL Frequency Controls designed for radio communication and navigation applications. This oscillator is capable of operating over frequency range from 0.05HZ to 40MHz and offers frequency resolution to within 1Hz. It is equipped with an adjustable temperature compensation function to minimize temperature effects on the oscillation frequencies. The product is available in two versions, with supply voltage of either 3.3V DC or 5V DC.

The SIT9002AI-28H25DD uses a dual-board architecture, which consists of a main board and a remote board. The main board incorporates all the necessary components such as the oscillator, voltage reference and control circuitry. The remote board contains the tuning capacitors and varactors which allow for precise frequency adjustment. The oscillator is able to accurately maintain its frequency within a specified temperature range.

The working principle of the SIT9002AI-28H25DD oscillator is simple. The main board supplies the required power to the oscillator circuit and the remote board supplies the tuning capacitors and varactors. When the voltage reference on the main board is adjusted, the capacitors and varactors on the remote board adjust the frequency of the oscillator. This frequency can be monitored via a digital input. By adjusting the voltage reference, the frequency of the oscillator can be precisely controlled.

The SIT9002AI-28H25DD is a versatile and reliable programmable oscillator which can be used in a variety of radio communication and navigation applications. Its frequency resolution and adjustable temperature compensation functions make it an ideal choice for demanding applications that require high frequency accuracy.
