SIT9005ACU1G-28DL

Programmable oscillators are a type of oscillator commonly used for a variety of applications. Programmable oscillators use a programmed or adjustable frequency, or frequency range, to achieve desired performance parameters. This technology allows for reliable and repeatable oscillation, thereby meeting the needs of both frequency stability and controlled performance.

The SIT9005ACU1G-28DL programmable oscillator is one such device and is widely used in a variety of applications, including: frequency-controlled RF systems, cellular communication, and clock control applications. It is a precision application-specific programmable oscillator that offers voltage controlled operation with temperature compensation, excellent harmonic suppression and stability.

Application Field and Working Principle

The SIT9005ACU1G-28DL is ideal for applications requiring low phase noise, ultra-low jitter and/or high accuracy frequency synthesis. It is designed for use in a range of industries, such as medical equipment, aerospace, defense, and commercial or industrial applications. It is particularly useful in critical timing applications where precise frequency control is required.

The SIT9005ACU1G-28DL utilizes a phase-lock loop (PLL) to adjust and maintain frequency references in an oscillator. In this configuration, the PLL loop has two main components: an input reference (VREF) and a feedback component that monitors and adjusts the output frequency. The VREF input can be generated from an external voltage source such as a crystal oscillator or synthesized clock. The feedback component monitors the output frequency of the oscillator and then adjusts the input voltage to maintain the desired frequency.

The SIT9005ACU1G-28DL is able to accurately adjust the output frequency from a given VREF in a very wide range of frequencies. The oscillator also features a proprietary temperature compensation circuitry that allows the output frequency to remain consistent over a large temperature range. This ensures that the device is able to perform reliably in different operating conditions.
