Programmable Oscillators are devices that provide a reliable, customised signal for a wide range of applications, from radio frequency (RF) transmission to clock generation for logic circuits. Among programmable oscillators, SIT9002AC-28H25ED is a unique model that offers a wide range of capabilities, due to its functionality and design. This article will discuss the application field and working principle of the SIT9002AC-28H25ED.

The SIT9002AC-28H25ED is a light, space-saving device, designed to fit all sorts of systems, from personal computers to embedded or mobile applications. It has a 24-bit frequency resolution, which makes it suitable for multi-GHz applications, and its 2.25V~5.5V operating voltage allows it to fit within different power-management designs. Its small size also makes it a great option for applications such as medical equipment, automotive systems, and security systems.

The SIT9002AC-28H25ED is designed with a USB interface, allowing for easy programming and remote control. Its programming options include frequency adjustment and adjustment on clock output and power output. This device can be used to generate precise and stable clock signals, with frequencies ranging from 33 MHz to 1.8 GHz. Furthermore, it has an output frequency accuracy of 1.0 ppm (parts per million) and clock output stability of ±2 ppm. This level of accuracy makes the SIT9002AC-28H25ED suitable for applications such as satellite navigation, cable communications, and control systems.

The working principle of the SIT9002AC-28H25ED is based on phase-locked loops. The device includes an oscillator and voltage-controlled oscillator (VCO), along with an amplifier and a loop filter. The VCO is used to generate signals with a wide frequency range, over which the oscillator is free-running to generate a clock signal. The output of the oscillator is then fed into the loop filter, where the frequency is compared to an externally provided reference signal. The loop filter is designed to provide a high level of linearity, enabling the device to achieve a high level of accuracy in the output clock frequency.

In summary, the SIT9002AC-28H25ED is a versatile device that offers a range of capabilities, making it suitable for a wide range of applications. Its frequency tuning range and accuracy make it suitable for high-frequency applications, and its design and size make it a great option for applications such as medical devices, automotive systems, and security systems. In addition, its use of phase-locked loops allows it to generate precise, stable output clock signals, making it a great choice for satellite navigation, cable communications, and control systems.
