Working Principle

The SIT9121AI-1CF-25E161.132800T oscillator is based on a patented temperature controlled crystal oscillator (TCXO) technology. The oscillator consists of two main components: a temperature controlled crystal oscillator and a frequency divider circuit. The TCXO is used to generate a stable reference frequency, which is then divided by the frequency divider circuit to generate the desired output frequency. The temperature controlled crystal oscillator accurately compensates for the variations in temperature to ensure a stable frequency output. The frequency divider circuit then takes this reference frequency and divides it by a programmable divider to generate the desired output frequency. The frequency divider circuit is also equipped with a programmable output enable pin, which allows the user to easily enable or disable the output of the oscillator.

The SIT9121AI-1CF-25E161.132800T oscillator also offers several other features, such as a low power consumption of 1.5mA, a 3.3V supply voltage, a low jitter output of 1ps RMS, and an integral voltage regulation circuit to ensure a stable power supply voltage. In addition, it offers several optional features, such as an input clock pre-divider, an automatic calibration mode, and an output signal strength setting, all of which further enhance the performance and reliability of this oscillator.

Overall, the SIT9121AI-1CF-25E161.132800T oscillator is a high performance oscillator that is designed for a variety of applications that require frequency dividing and clock generation. Its temperature compensated crystal oscillator provides stability with 0.005 ppm stability and 0.0001 ppm resolution. Its programmable divider and output enable pin make the ability to enable or disable the output easily. The low power consumption, 3.3V supply voltage, and low jitter output of 1ps RMS also ensure the reliable operation of the oscillator. Finally, the several optional features make it even more versatile, allowing the oscillator to address a variety of challenging requirements.
