Programmable Oscillators

Programmable oscillators are highly stable and accurate clock sources used in many applications, and the SIT9005ACR2G-25DD model is no exception. This model is a frequency-agile oscillator designed for use in the wired telecommunications industry. It functions through the synthesis of two reference frequencies, which can be adjusted to generate the desired output frequency and temperature stability. The oscillator consists of three separate sections — a reference frequency section, a synthesizing section, and an output buffer amplifier. Through careful tuning of the two reference frequencies, the SIT9005ACR2G-25DD can produce an output frequency range from 400 Hz to 1.79 GHz with excellent accuracy, jitter, and stability.

The reference frequency section of the oscillator consists of two highly reliable and accurate oscillators that are adjusted to precisely represent the desired output frequency. In order to maintain this accuracy, it is important that the oscillator is designed to have a low phase noise and temperature stability so that it is not affected by environmental changes. The reference oscillator must also be highly resistant to shock and vibration, as it is part of a sensitive and expensive instrument. The SIT9005ACR2G-25DD model solves this issue by incorporating a K6U series temperature-compensating crystal oscillator, which offers excellent stability in both temperature and shock/vibration environments.

The second part of the oscillator is the synthesizing section, which is responsible for translating the reference frequency into a desired output. This is accomplished by using a phase-locked loop (PLL) to generate the appropriate frequency. The PLL utilizes the crystal oscillator\'s output as the reference signal and causes the synthesizing section to produce the output frequency desired by adjusting the phase and frequency of the feedback signal. This feedback signal is then amplified by an output buffer amplifier, which ensures that the PLL\'s output is stable and reliable. The SIT9005ACR2G-25DD model is specifically designed to produce excellent accuracy, jitter and stability with very low phase noise and is capable of outputting frequencies between 400 Hz and 1.79 GHz.

The SIT9005ACR2G-25DD model proves to be an excellent choice for many applications due to its reliable, accurate and stable performance. It is used in numerous applications in the wired telecommunications industry, such as mobile phones, satellite communication systems, radiofrequency data links, and microwave network interfaces. Additionally, this oscillator is utilized in military, medical, and experimental applications which require precision timing and accurate output frequency. The exceptional performance and versatility of this oscillator has helped revolutionize how we communicate, and the SIT9005ACR2G-25DD model continues to be one of the most reliable and popular oscillators in the industry.
