SIT9005ACB1G-18NE

Programmable oscillators are frequency-controlled electronic circuits used to produce a constant oscillation waveform over a range of frequencies. They are designed to provide stable output waveforms, regardless of temperature changes and transient power supply levels. The SIT9005ACB1G-18NE is a type of programmable oscillator designed to meet requirements within industrial, commercial, and communication applications.

The SIT9005ACB1G-18NE oscillator has a wide frequency range from 2 MHz to 18 GHz, with a voltage controlled tuning range from -10°C to +60°C and an operating temperature range from -40°C to +85°C. Additionally, it has an ultra-small 14-pin package, low-jitter output, and a 6-MHz frequency resolution. These features make it ideal for applications that require precision control of their oscillations, such as radio transmitters, receivers, and radar systems.

The oscillator is powered by a voltage input of +3V to +5.5V, or up to +16V. A static control voltage determines the frequency at which the oscillator starts, while a DC voltage tunes the frequency up or down. The oscillator is designed to remain stable over slight variations in temperature and power supply voltage levels. Typically, the SIT9005ACB1G-18NE requires an input control voltage of 0V to +2V.

The SIT9005ACB1G-18NE employs a special phase-locked loop (PLL) architecture to maintain a constant oscillation frequency, independent of the device\'s temperature or power supply noise. This PLL architecture includes a voltage-controlled oscillator (VCO), a frequency divider, which divides the VCO\'s output frequency by a fixed or configurable amount, and a phase detector, which compares the divided output frequency with a reference source. The phase detector can then adjust the VCO\'s frequency in order to match the reference signal.

The SIT9005ACB1G-18NE also incorporates an on-chip tuning voltage signal amplifier, which amplifies an input voltage to control the oscillator frequency. This signal amplifier can provide a wide tuning range, up to +2V. In addition, the oscillator features a digital calibration function, as well as low power consumption and a high signal-to-noise ratio.

The SIT9005ACB1G-18NE is a versatile and reliable programmable oscillator that can be used in a wide variety of applications, including radio transmitters and receivers, radar systems, and other communications and industrial applications. Its wide frequency range, low-jitter output, and high signal-to-noise ratio enable it to meet the most demanding requirements of these applications.

The SIT9005ACB1G-18NE also offers a number of advanced features that make it an ideal choice for advanced applications. These features include a digital calibration functional, an on-chip signal amplifier, and a PLL architecture that ensures a constant frequency output, regardless of temperature and power supply noise. Furthermore, the oscillator is designed to operate with low power consumption and is supplied in an ultra-small 14-pin package.
