Programmable oscillators play a very important role in today’s electronics circuit design. They are used to replace devices such as oscillators, crystal oscillators, and quartz crystal oscillators, and can provide improved accuracy, resolution, and repeatability. One such product is the SIT9005ACR1D-30DK programmable oscillator.

The SIT9005ACR1D-30DK programmable oscillator is a high-performance frequency synthesizer with a programmable frequency resolution of up to 200 MHz and a maximum frequency of about 3GHZ. The device utilizes a low-noise, low-power PLL (Phase Locked Loop) circuit, which provides high accuracy, low jitter, and excellent long-term stability. The oscillator also features a precision temperature-compensated voltage controlled temperature source (VCTCXO) and a wideband voltage-controlled oscillator (VCO) with very low phase noise. This versatility makes the SIT9005 suitable for a wide range of applications including communications, satellite, and aerospace systems.

SIT9005ACR1D-30DK is programmable, making it ideal for many applications that require precise frequency control and signal generation. It is particularly suitable for applications with very high accuracy requirements, such as in the medical, aerospace, and military fields. Additionally, the excellent performance of the SIT9005, combined with the on-board digital-analog conversion provide a flexible solution for precision frequency synthesizers.

The working principle of SIT9005ACR1D-30DK is based on the PLL circuit. The PLL circuit uses a reference signal, typically generated by a quartz crystal oscillator, to control the frequency of the programmable oscillator. The PLL circuit utilizes a phase detector, a filter, and a voltage controlled oscillator (VCO) to control the frequency of the output signal It also involves a phase-frequency detector to synchronize the phase and frequency of the output signal with the phase and frequency of the reference signal.

The output frequency of the SIT9005ACR1D-30DK is determined by the programmable frequency resolution of the device. This can be adjusted using the on-board digital-analog converter (DAC). The DAC is connected to the PLL circuit and can be programmed to adjust the frequency of the reference signal. Once the reference frequency of the PLL is set, the oscillator will generate an output signal at the desired frequency with very high accuracy and repeatability.

In conclusion, the SIT9005ACR1D-30DK programmable oscillator is a versatile and reliable frequency synthesizer with high accuracy, resolution, and repeatability. It is suitable for a wide range of applications and can provide excellent performance in fields such as medical, aerospace, and military. The device utilizes a PLL circuit to generate the output signal and a digital-analog converter (DAC) to adjust the frequency resolution.
