Programmable Oscillators are electronic oscillators whose frequency can be programmed without changing the internal circuitry or moving parts. They come in various forms, including voltage-controlled oscillators (VCOs), programmable crystal oscillators (PCXOs), and temperature-controlled oscillated (TCXOs). The SIT9002AI-33H33SD is a programmable oscillator designed and manufactured by Silicon Systems, Inc.

Application Field and Working Principle

The SIT9002AI-33H33SD is used in a variety of applications, including frequency selection in cellular systems, automatic test equipment, point-of-sale systems, scientific instrumentation, and avionics. It is particularly popular among designers who require precision frequencies in their designs.

The SIT9002AI-33H33SD is equipped with features that make it ideal for use in such applications. It features an integrated voltage regulator, on-board temperature compensation, digital control functions, and a voltage range of 0 to 5.5 volts. This enables it to provide a highly precise, stable, and robust output frequency across temperature, voltage, and humidity ranges.

The working principle of the SIT9002AI-33H33SD is based on the combination of a resonator and a frequency-selective phase-locked loop (PLL). The resonator is a tuned electronic device that produces a stable and repeatable frequency when connected to a source of electrical power. The PLL works to match the frequency of the resonator with the frequency of an external signal. The external signal can either be a fixed frequency or a frequency that can be programmed.

The combination of the resonator and the PLL allows the SIT9002AI-33H33SD to generate precise frequencies with very high accuracy. Furthermore, the programmable frequency can be easily adjusted by applying a voltage to the device. This allows the device to be tuned to the exact frequency that the user requires.

The SIT9002AI-33H33SD is also rated to operate over a wide temperature range of -40 to +85 degrees Celsius. This makes it an excellent choice for designers who need to maintain precise frequency control in harsh or extreme environments. Furthermore, its low power consumption makes it a great option for applications that require extended battery life.

Overall, the SIT9002AI-33H33SD is a versatile and reliable programmable oscillator. Its robust design, wide operating temperature range, and precision tuning make it an ideal choice for various applications that require a precise and stable frequency. Furthermore, its low power consumption and robust features make it an excellent choice for designers who require a reliable oscillator for their projects.
