Introduction:
Programmable oscillators, also known as PLL oscillators, are components that are used to generate an output signal at a certain frequency. One of these components is the SIT9005ACR1D-18NI, a voltage-controlled oscillator (VCXO) with frequency range between 16MHz to 18.5MHz and a maximum frequency deviation of +/-1.75MHz. This component is ideal for applications which require precise control of frequency and accuracy of performance.

Application Field:
The SIT9005ACR1D-18NI is a wide-ranging component that can be used in a variety of applications. It is primarily used in communications systems, such as mobile phones and other wireless communication devices, as well as in commercial communications networks. It is also used in digital set top boxes, satellite receivers, and broadcast radio receivers. In addition, it is used in automotive, medical, and military applications. It is also increasingly used in consumer electronics for audio and video signals, due to its ability to control high-frequency signals over a broad range of frequencies.

Working Principle:
At the heart of the SIT9005ACR1D-18NI is a voltage-controlled oscillator (VCXO) which uses a referenced oscillator to generate an output signal at a certain frequency. It works by controlling the frequency of the output signal with an external voltage. The VCXO pulls the frequency up or down, depending on the applied voltage. The range of the frequency adjustment is controlled by the supply voltage, with an adjustment range of +/-1.75MHz. In addition, the voltage control pin is also used to provide a more precise output frequency.

Conclusion:
The SIT9005ACR1D-18NI is a versatile voltage-controlled oscillator (VCXO). It has a wide range of applications in communications systems, digital set top boxes, satellite receivers, and consumer electronics for audio and video signals. It is also increasingly used in automotive, medical, and military applications. It works by controlling the frequency of the output signal with an external voltage and has an adjustment range of +/-1.75MHz. The voltage control pin can also be used to provide a more precise frequency output.
