The SIT3822AC-1B-25NY offers a variety of features that make it an ideal choice for many different applications. It features high frequency stability and low jitter, making it suitable for use in applications that require precise timing such as frequency synthesis, clock generators and signal processors. It also comes with a wide input voltage range and an improved accuracy of +/-5-percent. Furthermore, the device has a high-reliability and temperature stability over the -40 to +85 degree Celcius range.

Working Principle

At the heart of the SIT3822AC-1B-25NY is a quartz crystal resonator, which is a delicate and precise piece of quartz that is encased in a protective outer container. This crystal resonator is responsible for the device’s frequency stability and low jitter. As the vibrational frequency of the crystal is changed, the frequency of the output signal is changed accordingly.

The SIT3822AC-1B-25NY utilizes a frequency-tuning scheme that allows the user to rapidly and accurately tune the device to the desired frequency. This scheme relies on an integrated circuit, which is connected to the crystal resonator and allows it to be tuned electronically without the need for any external components. As the voltage across the circuit changes, the resonant frequency of the crystal changes accordingly.

The SIT3822AC-1B-25NY also features a digital frequency lock to ensure that the device remains at its target frequency. This digital lock is implemented using a phase-locked loop circuit, which measures the phase difference between the input signal and the output signal, and then adjusts either the input or the output frequency to bring them back into alignment. This results in precise and stable frequency control regardless of changes in temperature or voltage.

In summary, the SIT3822AC-1B-25NY is a high-performance programmable oscillator that can be used in a variety of applications due to its wide frequency range, precise timing and reliable operation. Its crystal resonator, frequency-tuning schemes and digital frequency lock make it an ideal choice for precision applications such as avionics, instrumentation, medical and robotics.
