Programmable Oscillators are electronic components used to produce oscillating electrical signals, such as sine waves, square waves, and triangle waves, as well as providing frequency stability, low noise, minimal distortion, and excellent phase noise properties. The SIT9005ACE2H-XXDB Programmable Oscillator is particularly suitable for applications requiring high accuracy, high stability, low jitter and wide frequency range with a small package size.

The SIT9005ACE2H-XXDB is a three-electrode quartz crystal oscillator which uses an internal oscillation signal (L-C) circuit, also known as Pierce Oscillator. It is a PCM (programmed-crystal oscillator) type with automatic frequency correction based on its temperature characteristics. The integral frequency programmer allows the design to be easily changed without any external adjustments or special components.

The SIT9005ACE2H-XXDB is designed to be used in low-frequency (2 to 400MHz) embedded applications, particularly in automotive and telecommunications. Some of the main applications of this product include time-division multiplexing (TDM) systems, digital signal processing systems, clock signal generation, microprocessor and bus clock sources, and frequency synthesizer applications.

The SIT9005ACE2H-XXDB utilizes a series of frequencies for use in its applications. The high output frequency range is 200 to 400 MHz with a frequency deviation of ±20ppm (max) over a temperature range of -40 to +85°C. The special mounting type provides stability up to ±30ppm (max). The output load is ensures that the device is accessible with a range of 50Ω impedance.

The SIT9005ACE2H-XXDB Programmable Oscillator is equipped with two separate oscillators, one for the feedback loop and another for the reference signals. The first oscillator controls the output frequency and the other provides a stable reference signal for the control circuit. The reference oscillator is a crystal oscillator, which provides a reliable and accurate frequency for the output signals. This eliminates the need for a voltage-controlled crystal oscillator (VCXO) or a temperature-compensated crystal oscillator (TCXO). The two oscillators are then combined in such a way that the temperature stability of the feedback loop and the accuracy of the reference oscillator compensate each other, resulting in excellent frequency stability over temperature.

The SIT9005ACE2H-XXDB Programmable Oscillator can also be used in a voltage-controlled (VCXO) mode. This mode allows a very wide tuning range of up to ±120ppm. This feature is useful in applications such as frequency synthesizers where a wide frequency-tuning range is essential. Additionally, the low noise, low phase noise, minimal distortion and excellent phase noise properties make this product suitable for use in precision applications, such as frequency synthesizers, where accuracy and stability are of the utmost importance.

The SIT9005ACE2H-XXDB Programmable Oscillator is a reliable, low-cost, high-performance product for use in a variety of embedded applications. Its excellent frequency stability and minimal distortion make it an ideal choice for applications requiring high accuracy and excellent phase noise properties. With its two oscillators, the product provides an excellent frequency-tuning range, making it highly suitable for use in frequency synthesizers and other precision applications. Furthermore, its small package size makes it a great choice for embedded applications, such as TDM systems, digital signal processing systems, clock signal generation, and microprocessor and bus clock sources.
