Programmable oscillators are special types of oscillators designed for applications requiring the ability to configure or reprogram the oscillator’s frequency and other parameter settings. One such programmable oscillator is the SIT9002AC-33N33DB, which is designed for use in hightemperature as well as high humidity and vibration environments. This article will discuss the application field and working principle of the SIT9002AC-33N33DB programmable oscillator.

The SIT9002AC-33N33DB is a low-voltage programmable oscillator designed mainly for clock applications in memory cards and other portable devices. It has a frequency range of 0.3 MHz to 80 MHz, and operates over a wide range of temperatures (–40 to +85 °C). It also features built-in protection so that it can withstand any sudden increase in voltage or extreme temperature changes. Furthermore, it is designed to be highly reliable and can withstand shock and vibration up to 2000 G.

The SIT9002AC-33N33DB programmable oscillator can be used in a variety of applications in which precise frequency control is required. For example, it can be used in precision timing and clock source for microcontrollers, in medical imaging, and in automotive media players. It can also be used in communications systems, where it can be used for frequency agile synthesis. Additionally, this oscillator can be used in wireless application, such as Wi-Fi routers, LTE modems, and 5G vehicles.

At the heart of the SIT9002AC-33N33DB programmable oscillator is the DigiWare pull-in frequency technology. This patent-pending technology combines a numerical optimization algorithm with a classic digital phase-locked loop (DPLL). The digital optimization algorithm uses the actual frequency of the applied signal to rapidly determine the optimal phase and frequency settings. The DPLL then uses these settings to lock onto the applied signal for precise timing.

In addition to the pull-in frequency technology, the oscillator has a built-in programmable output voltage control. This feature allows the user to adjust the output voltage from 0.8 to 3.3V. The output voltage can also be adjusted between steps in 20 mV increments. The device also features a programmable output frequency range, which can be adjusted from 0.3 to 80 MHz.

The SIT9002AC-33N33DB programmable oscillator is also equipped with an on-chip temperature sensor, which can sense the ambient temperature and adjust the oscillator’s frequency accordingly. This feature is particularly useful for applications where temperature sensitivity is critical, such as in communication and data storage systems.

Overall, the SIT9002AC-33N33DB is a versatile and reliable programmable oscillator designed for use in a variety of applications. Its high accuracy, wide temperature and voltage range, and its built-in protection make it suitable for use in harsh environmental conditions. Furthermore, its advanced pull-in frequency technology and on-chip temperature sensor make it an ideal choice for applications requiring precise frequency control and temperature sensitivity.
