Programmable oscillators have been a familiar technology for many years and they have become an essential part of many electronic systems. The SIT9002AC-33H18DG is one of the newest programmable oscillators on the market. This oscillator is designed to provide a wide range of frequencies, with a tuning accuracy of ±0.5%. In addition, the SIT9002AC-33H18DG has the capability to operate between two discrete frequencies and offers a relatively high pulse-width accuracy.

The SIT9002AC-33H18DG application field includes the use in communications, media, handheld wireless products, portable medical equipment, and instrumentation. For example, it is suitable for applications that require a fast frequency switch from one frequency to another with minimal distortion or loss of signal quality. It can also be used as a low-cost replacement for applications that require a stable frequency in the order of 10kHz for a long time. In addition, this oscillator is often used in conjunction with other components to provide pulse modulation or frequency division.

The SIT9002AC-55H18DG is a high-performance programmable oscillator that combines high accuracy, stability and reliability with low power consumption. It features an integrated phase-locked loop (PLL) frequency synthesizer which offers a higher level of accuracy and stability than traditional discrete PLL designs. The PLL allows for precise frequency control, and enables users to program any frequency up to 18 GHz with a resolution of 0.1 Hz. The oscillator also includes a built-in voltage-controlled oscillator (VCO) with a range of 7MHz to 18GHz.

The oscillator also includes an integrated frequency counter, which is used to measure and adjust the output frequency. The frequency counter uses pulse-width measurement to provide an accurate and stable frequency reference, and can also be used to set the VCO frequency. Additionally, the oscillator has a 1PPS input for an external frequency reference, which can be used to synchronize the frequency output. This feature can be particularly useful for applications that need precise frequency control.

The working principle of the SIT9002AC-33H18DG is simple yet efficient. When powered on, it generates the desired frequency output by using pulse-width modulation. The pulse-width modulation is achieved by varying the width of the signal output by changing the oscillator’s duty cycle. The frequency counter helps to ensure accuracy, as it allows the oscillator to respond more quickly to changes in the environment. Additionally, the frequency counter also provides precise measurements that minimize frequency errors.

Overall, the SIT9002AC-33H18DG is a reliable and precise programmable oscillator that is suitable for a wide range of applications. Its ability to provide highly accurate frequency control with minimal distortion and loss of signal quality makes it an ideal solution for many applications. The built-in frequency counter also helps to ensure accuracy and stability, and the ability to use an external frequency reference for precise synchronization makes this oscillator even more attractive.
