Due to its unique design and programmability, SIT1602AIU1-25E makes it ideal for applications where parameters such as frequency, VCO range, output voltage and enable must be precisely controlled. In power-moderating and timing applications, this oscillator is used to precisely control the switching frequency and thus reduce power consumption, while in automotive and aerospace applications it is used to precisely synchronise the operation of multiple systems.

Working Principle

SIT1602AIU1-25E utilizes a unique technique called programmable-flexible-demand technology, or PFD for short. This technology enables the oscillator to generate precisely tuned signals that can be used for a variety of applications. This technology is based on the principle of circuit parameter demands, which allows for the precise tuning of the oscillator. Basically, the PFD technology uses two different functions to achieve precise frequency control: the reference voltage control register and the frequency setting register.

The reference voltage control register is responsible for setting the reference voltage that is used to control the oscillator’s frequency. This is done by controlling the voltage applied to the main components of the oscillator. This register can be programmed to produce a range of reference voltages, allowing for precise tuning of the output frequency.

The frequency setting register, on the other hand, is responsible for controlling the frequency of the output signal. This register is programmed to set the frequency in the range of 0.5 to 400 MHz. The PFD technology enables precise and on-demand adjustment of the output frequency by programming the frequency setting register without affect other parameters, such as phase noise, jitter and turnover.

Conclusion

SIT1602AIU1-25E is a programmable oscillator that is ideal for a variety of applications from embedded analog systems, to power-moderating and timing, to automotive and aerospace systems. It utilizes a unique programmable-flexible-demand technology that enables precise tuning of the output frequency without affecting other parameters, such as phase noise, jitter and turnover.

This oscillator is one of the most versatile and reliable options available on the market, and thus provides a great solution for those applications where precise and on-demand adjustment of the output frequency is vital. With its highly reliable performance and wide application field, SIT1602AIU1-25E is quickly becoming the go-to oscillator of choice in the industry.
