Programmable oscillators are electronic components that generate AC signals, typically within the range of 10 to 2500 MHz. The main purpose of a programmable oscillator is to use a single type of signal generation device to provide different frequency and duty cycle signals. The types of these programmable oscillators include various timing solutions such as clock oscillators, VCXO (Voltage Controlled Crystal Oscillator), TCXO (Temperature Compensated Crystal Oscillator), and OCXO (Oven Controlled Crystal Oscillator).

SIT9005ACU2G-XXEB is one of the typical programmable oscillators which belong to the OCXO family. It represents the OCXO performance and miniature size both in the same component. This programmable oscillator is offered in several frequency ranges and is suitable for many applications due to its low jitter performance and superior stability.

The application fields of the SIT9005ACU2G-XXEB mainly include frequency synthesis, timing and frequency control, military and secure communications, high frequency tailoring, and instrumentation. This component is also used for industrial and portable applications where superior oscillator performance over temperature is crucial. Its great performance makes this component widely applies in the radio broadcasting, digital television, satellite receiving, and FM broadcast system involvements.

The SIT9005ACU2G-XXEB is designed in low noise and low phase noise technology with fast start-up time, low phase noise and excellent high frequency phase noise. It is also designed with a built-in voltage-controlled crystal oscillator (VCXO) and fully integrated temperature control circuitry that provide superior jitter, high temperature stability and improved phase noise characteristics over time. This component also features a 0 to 10V controller and an adjustable crystal load-capacitance, enabling it to achieve very high performance and dynamic range.

In terms of the working principle of the SIT9005ACu2G-XXEB programmable oscillator, it mainly relies on the mechanical resonance of a crystal or quartz crystal. This component contains three main parts: a quartz crystal, an oscillator circuit, and a frequency control circuit. The quartz crystal vibrates at a frequency determined by its size and construction. An oscillator circuit then amplifies the vibration from the quartz crystal, creating a stable output frequency. Finally, a frequency control circuit allows the output frequency to be adjusted by applying either a voltage or current stimulus to the crystal.

The SIT9005ACU2G-XXEB programmable oscillator is ideal for applications that require superior jitter performance, high-temperature stability, and excellent high-frequency phase noise characteristics. Its small size, fast start-up time, and performance make it an increasingly popular choice for both industrial and portable applications.
