Programmable oscillators are the the most convenient and most efficient solution for many applications that require a stable and repeatable reference frequency source with a controlled accuracy, phase and output amplitude. SIT9005ACL1D-XXEB is one of the advanced programmable oscillators available in the market, featured with exceptional phase noise performance and high output stability over wide temperature and voltage ranges. In this article, we will discuss the application field and working principle of the SIT9005ACL1D-XXEB.

The SIT9005ACL1D-XXEB can operate from a wide variety of frequencies between 4.395MHz to 244.595MHz and provides output power up to +5dBm. It is designed to be used in a variety of applications such as industrial equipment, avionics, and medical equipment. The SIT9005ACL1D-XXEB has low phase noise and tight frequency accuracy, making it ideal for various types of application. It can be operated in temperature range of -40°C to +85°C, and with supply voltage range of 3.3V to 4.9V.

The SIT9005ACL1D-XXEB includes an oscillator circuit and several programmable components used to tailor the oscillator waveform in order to provide a better frequency stability and accuracy. The SIT9005ACL1D-XXEB utilizes a frequency synthesizer integrated circuit (IC) which includes a Phase Locked Loop (PLL), a Voltage Controlled Oscillator (VCO), and programmable dividers. The oscillator circuit is designed for output waveform linearity, temperature and power supply sensitivity, and does not require any external components.

The PLL is used to monitor the frequency accuracy of the SIT9005ACL1D-XXEB and maintains it within the required specifications in order to ensure stable frequency operations. It includes a reference frequency source and control logic. The reference frequency source is used to provide a reference frequency signal, with which the VCO is compared in order to maintain the oscillator frequency within the required accuracy. The control logic uses the difference in signal strength between the reference frequency and the VCO output in order to adjust the oscillator frequency. The VCO is the main oscillator circuit and provides the output signal from the SIT9005ACL1D-XXEB. The VCO is designed to vary its frequency in accordance with the control signal from the PLL and provide stable and precise reference frequencies.

The SIT9005ACL1D-XXEB also features an output divider which allows the user to program the output frequency to one of several different discrete frequencies. The divider divides the output of the VCO by an integer value, resulting in an output frequency with a predetermined ratio of the selected VCO frequency. The divider can be programmed to provide different output frequencies depending on the application requirements. The output divider is also used to reduce spurious harmonics, resulting in a much cleaner output signal with better accuracy and phase noise characteristics at higher frequencies.

In addition, the SIT9005ACL1D-XXEB also includes programmable output amplitudes. The output amplitude control allows the user to adjust the output power, ensuring that the signal is compliant with the application\'s power requirements. This feature is especially useful in applications where the output power must be adjusted in order to reduce interference or to improve signal-to-noise ratio.

The SIT9005ACL1D-XXEB is a highly advanced programmable oscillator which offers exceptional phase noise, tight frequency accuracy, and high output stability over wide temperature and voltage ranges. It is ideal for many applications requiring a stable and repeatable reference frequency source with a controlled accuracy, phase and output amplitude. With its wide range of features and its ability to be programmed to the desired frequency and output power, the SIT9005ACL1D-XXEB is an excellent choice for many different types of applications including avionics, industrial equipment, and medical equipment.
