Programmable oscillators are a type of electronic oscillator that can be programmed to produce a custom waveform, frequency, and phase relationship. The SIT9005ACU2H-XXSP is an example of a programmable oscillator that can be used in a wide variety of applications. This article will discuss the application field of this programmable oscillator and its working principle.

The SIT9005ACU2H-XXSP programmable oscillator can be used in mobile handsets, consumer electronics, and industrial control systems, as well as applications requiring high accuracy and reliable operation. Its wide operating range and high quality performance provide a reliable timing solution for any application. The oscillator has a built-in program control that allows it to generate frequencies between 5 Hz and 24 MHz, with a resolution of up to 0.2 ppm. Additionally, it has a low current consumption of 1.5 mA and a wide operating temperature range of -40°C to +105°C.

The working principle of the SIT9005ACU2H-XXSP is based on a voltage-controlled oscillator (VCO) and a current-controlled oscillator (CRO). The VCO produces a variable frequency signal that is proportional to the voltage applied to it. The CRO is used to control the frequency of the oscillator. The output of the oscillator is generated by connecting these two oscillators in series. The frequency of the output can be programmed by adjusting the voltage and current inputs to the VCO and CRO, respectively.

The oscillator also includes an on-board phase locked loop (PLL) to provide phase locked frequency tuning. The PLL allows the frequency of the oscillator to be precisely tuned by changing the voltage at the input and output terminals without affecting the output amplitude. This makes it possible to tune the frequency of the oscillator over a wide range and also keeps the output waveform stable. The oscillator also has an adjustable output buffer that can be used to adjust the impedance of the output.

The SIT9005ACU2H-XXSP is an extremely versatile programmable oscillator that can be used in a wide variety of applications. Its wide operating range and high quality performance make it an ideal choice for any application requiring a reliable timing solution. Additionally, the built-in program control and phase locked loop make it capable of producing highly accurate and stable frequencies over a wide range. As such, the SIT9005ACU2H-XXSP is an excellent choice for any application requiring a programmable oscillator.
