The SIT9005ACR2H-18DN is a programmable oscillator that utilizes a CMOS oscillator, particularly a voltage-controlled oscillator (VCO). It is designed for applications such as frequency synthesis, RF systems, and synchronous detection. The SIT9005ACR2H-18DN is designed to feature a high accuracy and low jitter performance, allowing for accurate capture and synchronization for applications such as frequency synthesis, test and measurement and communication systems.

The SIT9005ACR2H-18DN has an operating temperature range from -40°C to +125°C and a frequency range of 1MHz to 18GHz, which is suitable for applications across a wide range of frequencies.

The SIT9005ACR2H-18DN is a programmable oscillator, which means that it is able to be programmed to a particular frequency level, or to a particular frequency range with a minimal input voltage. In other words, it can be programmed or adjusted to generate an oscillation at a desired frequency level. In addition, it can be programmed to generate a frequency range, which is primarily used to detect and measure changes in frequency (such as frequency modulation).

The SIT9005ACR2H-18DN utilizes two separate inputs, a control voltage input and a control voltage range input. The control voltage input is used to adjust the oscillator\'s output frequency, while the control voltage range input determines the operating range of the oscillator. The combination of these two inputs allows the SIT9005ACR2H-18DN to be programmed to different frequencies, as well as different frequency ranges, based on the specific requirements of the application.

The output of the SIT9005ACR2H-18DN can be configured to operate in either single-ended or differential mode. In single-ended mode, it can be programmed to generate an output frequency between 1.4MHz and 3.2GHz, while in differential mode, it can be programmed to generate an output frequency between 1.4MHz and 18GHz. Additionally, the SIT9005ACR2H-18DN has an output phase noise of -169 dBc/Hz (at 1kHz offset) to ensure clean output signals in applications such as frequency synthesizers and digital clock sources.

The SIT9005ACR2H-18DN utilizes an onboard voltage regulator, which allows it to be powered by a wide range of power sources, including PDAs and laptops, as well as external power supplies. It also includes a monitoring pin, which can be used to monitor the supply voltage, condition, and trigger the oscillator. In addition, it utilizes an adjustable current limiting feature to protect against accidental over voltage.

In summary, the SIT9005ACR2H-18DN is a programmable oscillator designed for applications in frequency synthesis, RF systems, and synchronous detection. It has an operating temperature range from -40°C to +125°C and a frequency range of 1MHz to 18GHz, and it can be programmed with a minimal input voltage to generate an oscillation at a desired frequency level or within a given frequency range. Additionally, it has an output phase noise of -169 dBc/Hz (at 1kHz offset) to ensure clean output signals. Finally, the SIT9005ACR2H-18DN is powered by an onboard voltage regulator and features an adjustable current limiting feature for protection against over voltage.
