Programmable Oscillators are devices which offer a variety of output frequencies allowing users to adjust the output frequency precisely, making them suitable for a wide range of applications. The SIT9005ACL1G-XXDF is a programmable oscillator that is suitable for use in both small form factor (SFF) applications as well as professional laboratory applications. This article will discuss the application field and working principle of the SIT9005ACL1G-XXDF.

The wide-temperature range programmable oscillator is a great choice for those applications which require absolute precision and stability over a wide temperature range. It is capable of delivering excellent performance spanning from -40°C to +85°C. The oscillator is a highly integrated device combining a temperature controlled oscillator, frequency discriminator and a frequency temperature manager. It uses a long-term stability sub-loop to offset relative instability due to pathological effects like aging, temperature and loading. This makes it ideal for applications such as phase-locked loop synthesizers, transmit/receive sychronization, PLL-based frequency synthesizers and reference clocks.

The SIT9005ACL1G-XXDF utilizes patented frequency control technology called HFMA (Harmonically Forced Modulated Auto Frequency Adjustment). This technology adjusts the frequency of the oscillator in real-time based on the temperature of the environment. The oscillator is also highly accurate and stable, with a maximum frequency error of 10ppm, making it suitable for use in ultra-precision applications. The oscillator also offers low power consumption and high reliability, making it an ideal choice for those applications requiring high-quality signals over a wide temperature range.

The oscillator consists of four different modules: a temperature-controlled oscillator (TCO), frequency discriminator (FD), frequency temperature manager (FTM), and output control unit (OCU). The TCO generates a sine-wave signal, which is then fed into the FD for frequency analysis. The FD then evaluates the frequency and compares it to a target frequency. If the frequency is within an acceptable range, the signal is sent to the FTM, which is responsible for offsetting long-term instability due to age and temperature changes. Finally, the signal is sent to the OCU, which adjusts the output frequency based on the specified temperature range.

In summary, the SIT9005ACL1G-XXDF Programmable Oscillator is an excellent choice for a wide range of applications requiring absolute precision and stability over a wide temperature range. It utilizes patented HFMA technology to adjust the frequency of the oscillator in real-time based on the temperature of the environment, offering excellent accuracy and stability with a maximum frequency error of 10ppm. The oscillator also offers low power consumption and high reliability, making it an ideal choice for those applications requiring high-quality signals over a wide temperature range.
