Programmable oscillators produce a variety of frequency, the frequency range is usually wide and they usually have a high accuracy and stability. The SIT9005ACU2D-33DA is an example of this type of product which is being used increasingly in a variety of applications.

The SIT9005ACU2D-33DA is a programmable oscillator with excellent precision and stability. The oscillator is based on a proven AT-Cut quartz resonator and produces a frequency range from 40.96 MHz to 140.00 MHz. The accuracy is up to 0.5 PPM with a low phase noise of -75 dBc/Hz at 1 kHz offset. It also boasts a low phase jitter of around 0.2 PSR-RMS at 10 kHz offset. The device is RoHS compliant.

The SIT9005ACU2D-33DA has many uses in a variety of applications. It is particularly suited to television broadcast, wireless communications, radio test and measurement, and navigation applications. Its precise and stable output makes it ideal for precise frequency control in communication systems and precise timing such as GPS systems. In addition, it can also be used in low jitter and wideband applications such as clock dividers, frequency synthesizers and other frequency control circuits.

The working principle of this device is based upon the quartz crystal resonator. A quartz crystal works by vibrating in response to an applied voltage or a force. The resonant frequency of this crystal is determined by the physical dimensions and by the material it is made from. When an alternating voltage is applied to the crystal, the resonator vibrates at a rate determined by its resonant frequency. This rate is monitored and regulated by the electronics on-board the SIT9005ACU2D-33DA.

The oscillator is also programmable, so that the frequency can be changed to suit the application. This is done using a variable resistor (potentiometer) which is used to adjust the capacitance of the resonator. This method of programming allows for a wide frequency range and is effective for applications where the frequency needs to be changed quickly. The SIT9005ACU2D-33DA also features a power-on reset, which ensures that the frequency is set to the correct value after power-on.

In summary, the SIT9005ACU2D-33DA is an accurate and reliable programmable oscillator with a wide frequency range and low phase noise. It has many uses, particularly in applications where precise frequency and timing control is required. Its programmable nature makes it an ideal solution for applications where the frequency needs to be changed quickly and easily.
